Just because someone makes a claim, in this case that the state owning the means of production means the resulting system is still capitalist as opposed to something else, does not make that claim a fact. Just because Marxists believe in state capitalism does not make their views fact. I fundamentally reject the notion that a state controlling the means of production is in any way the same as private ownership as the ways you can engage with private business and the state are very different.

Don’t make the mistake of thinking that a specific philosophy has the only valid definition of a concept.
