As a Mutualist, while there are a few things that could be better centralized, I'm in favor of a full worker consumer cooperative economy. Housing, groceries, and, utilities all work better as cooperatives, but capitalist have enough wealth to often push cooperatives out in other markets.

It's not linear. Anarchist or Libertarian Socialist systems like Syndicalism, Mutualism, Georgism, and Distributism are just as Socialist as Marxism in that they prevent the exploitation of capital accumulation, but they favor direct stakeholder ownership of firms in place of a state or other more communal systems that create an inherent hierarchy of power.

Capitalism ends where left begins.

I'm not sure if you're gatekeeping or just generalizing.
