a worker owned cooperative is the very definition of the workers owning the means of production, so i responded with marxist examples to your comment.

the fact that you assume that a country-wide implementation is the only way that marx's ideas can be implemented is a product of the red scare.

if organizing as cooperatives was the most common way to structure businesses (rather than a capitalist organization), then you'd have a different, arguably better society. in that situation, you can organize as a capitalistic endeavor if you want, but you'd have a hard time competing with co-ops for labor and other resources. it would be decentralized, entrepreneurs would still get rewarded, there would still be free enterprise, it would be a free labor market, etc.
