Worker-owned coops are the kind of Communism that a capitalist can really get behind. Good show. Also, Arizmendi Bakery is in fact delicious.
Except in communism it'd be the community (or, commune) that'd own the business. Since this is worker-owned, it's closer to syndicalism than communism (or socialism).
I worry about coops in the business world for the same reason. They have limited defense against massive corporations that decide they are enemies. But that's true of any small business.
