Being anti-capitalist doesn’t immediately imply being a communist. There are other alternatives to capitalism such as Economic Democracy.

This is also a straw man fallacy

I disagree. There are plenty of examples of liberal anti-capitalists such as David Ellerman

Capitalism is the opposite of democracy. In a capitalist firm, the managers are not accountable to the governed (i.e. workers). The employer is not a delegate of the workers. They manage the company in their own name not in the workers’ name. Managers do not have to have dictatorial control. It is entirely possible to have management be democratically accountable to the workers they govern as in a worker cooperative.

Capitalism v. Communism is a false dilemma. There are other options.

Capitalism is not just when the means of production are owned by individuals. For example, in an economy where all firms are democratically-controlled by the people that work in them, the means of production can be owned by individuals, but such an economy is not capitalist because exploitative property relations associated with capitalism are abolished

Socialism is not when the government does stuff, so those institutions are not examples of socialism. Anti-capitalists are arguing for the complete abolition of exploitative capitalist property relations that violate workers’ human rights.

This is a false dilemma. There are other alternatives to capitalism besides communism. It is entirely possible to have a non-capitalist non-communist system (e.g. an economy where every firm is democratically-controlled by the people that work in it)

This understanding of capitalism is a misunderstanding that both Marxists and neoclassical types share. It is not capital ownership that gives the employer the right to appropriate a firm’s whole product. The employment contract is what gives them that right. Sure, capital ownership affects bargaining power, but the root cause is that contract. Abolishing the employment contract while still having individual ownership is possible (i.e. a market economy of worker coops)

LVT taxes the unimproved value of land, so we are talking about land itself not what is built on top of it such as housing. Since land is a product of nature, the supply of it is perfectly inelastic

LVT taxing the empty lot next door at the same rate as a multimillion dollar hotel is exactly what makes it so efficiency enhancing because it give land owners economic incentives to use their land productively rather than just holding it and waiting for it to appreciate in value. With LVT, prices would exclude the value of the land.

LVT can be combined with other policies and taxes. You have to look at the whole package of policies to determine progressivity. LVT+UBI is progressive

It meets the definition of a progressive tax.

The broader Georgist program involves aggressive taxation of government-granted monopolies like IP, which both Musk and Bezos are indirectly beneficiaries of.

LVT is 1 policy meant to solve 1 problem. It can be combined with other policies that address other problems.

The labor theory of property, a negative application of which provides a moral rationale for LVT, also provides a justification for an inalienable right to worker democracy

Land value tax is progressive. Due to land’s inelastic supply, this tax cannot be passed on to others. People that own lots of land bear the entire burden of the tax. Charging for unimproved land value encourages building denser on more valuable land. This increases housing supply thus making housing more affordable

LVT is 1 policy. It can be combined with other policies. LVT is not an avoidable tax

Private ownership of labor implies the ability to alienate and transfer it for present or future benefits. Such a procedure is not possible because labor is de facto non-transferable. People can have private ownership over the products of labor, but they cannot own their labor because labor is inalienably theirs

Some Georgists don’t believe in ownership of labor because that inherently implies property rights in people. These Georgists recognize the same labor theory of property, which provides an ethical justification for common ownership of land and natural resources, also provides a critique of capitalist property relations and an argument for an inalienable right to workplace democracy.

Land value tax would solve this when combined with a UBI from the revenue it generates

You can’t fully experience liberty unless everyone is free

The whole product is the legal rights to the produced outputs and the liabilities for the used-up inputs not value. The employer legally owns the outputs and is legally liable for the used-up inputs.
FOSS can use quadratic funding. Not arguing for complete market abolition.
The workers are de facto responsible for production. By the principle that legal and de facto responsibility should match, the workers should jointly receive the whole product of the firm. The workers can delegate in a coop

Marx thought that control rights over the firm were attached to ownership of capital rather than being logically separately acquired in the employer-employee relationship.

“It is not because he is a leader of industry that a man is a capitalist; on the contrary, he is a leader of industry because he is a capitalist. The leadership of industry is an attribute of capital, just as in feudal times the functions of general and judge were attributes of landed property.” – Marx

Marx made mistakes though. For example, he assumed that the right of appropriating the whole product of a firm and control rights to direct the workers in the firm were attached to the ownership of capital. In reality, capital can be rented out just as labor can be hired. It is really the employer-employee contract that is at the core of capitalist appropriation. Ownership of capital just increases bargaining power to get favorable contract terms such as the employer contractual role

The employers’ claim extend beyond a cut. They solely appropriate 100% of the whole positive and negative product of the firm while employees as employees have 0% claim on the whole product

The latter problem could be solved by banning having non-member workers at the legal level and requiring giving workers voting rights in the firm they work in.

Worker coops don’t behave exactly like for-profit companies. Anti-capitalism is more than just worker democracy. For example, another aspect is common ownership of land and natural resources with fees for use. This would ensure that worker coops factor in environmental costs

What you are looking for is some sort of variant of quadratic funding. It is a mechanism that is specifically designed to overcome the free rider problem that public goods like FOSS suffer from. It solves it by matching private contributions to these public goods using a special formula that aligns incentives, so that everyone that knowingly benefits from a public good has an economic incentive to contribute to it because more contributors leads to a higher level of matching
