Ownership of productive property for accumulation of profit is the economic outcome of liberal ideals about the protection of all private property rights. I don't understand how liberalism can be anti-capitalist in practice. Capitalist accumulation means that the political power of capital overtakes any other. This is the historical reality. This is why liberal ideals have allowed the creation corporate personhood and free speech has resulted in no functional constraint of money in politics. This is how the process always plays out. If you are anti-capitalist, that is incompatible with the liberal ideals of absolute private property rights. That is a contradiction that many anti-capitalists highlight extensively.
