Uh no. Where are you getting these definitions?

The workers are private individuals, they own property privately. So even if they are part of a cooperative and each own a share of the company and all vote on its direction for example that’s still capitalism. The means of production is still privately owned.

Socialism is defined as a society with social ownership. You can do this a couple different ways. You can use the GPL model and licence something free for everyone. You can do what Canada has done with its water and other crown assets and declare they belong to everyone (which is why Nestle is trying to exploit it and American Nestle food products are going to go up in price thanks to terrifs). You can tax everyone and redistribute the assets in services and public works (but this requires a monopoly on violence). Or your culture can simply declare some or many things just can’t be owned. But the more collective ownership you have the more risk you run of dictatorship. No communist country has managed to pull off its classless ideal. In fact the closest examples I can think of are the First Nations with their various models of living in harmony with nature and not taking ownership of it in the first place. How can you own land if you constantly move around, let alone owning land in absentia. In fact I think Equador outlawed owning land in absentia outright so the concept isn’t that radical. But my point is social ownership isn’t just grabbing the means of production. A worker IS a capitalist. A business owner is a capitalist. A self employed independent contractor is a capitalist. Capitalism is not limited to big corporations and fat cats earning million dollar paycheques. Socializing ownership doesn’t negate that.

When does one stop being a “worker” and start being a “capitalist”? When they start their own business? When they make more than $15/hr? When they hire their first employee? When they bring in more than poverty wages? When they earn $10k a month? 50k? 500k? 1M? When does an individual trading goods and services become a “capitalist”? When do these “capitalists” seize the means of production if not through trade? And how would you propose to decentralize said means of production without violence save by through trade and innovation once more?

In short how would you propose to achieve decentralized ownership without the use of a monopoly on violence?
