The issue isn't philosophy. The roadblocks to worker-owned co-ops taking off are money and capital.
Picture a Venn Diagram of 2 circles:
(1) the circle of founders with some money (or don't have much money themselves but have the ability to get funds from investors) -- are not interested in forming worker co-ops. The founders want to own the business and hire employees to pay them wages.
(2) the circle of workers who want to share the ownership in a co-op don't have the money to fund the business.
Those 2 circles do not intersect for the most part. There isn't any alignment between the founders-with-money who want employees -- and -- the workers-without-money who want co-ops.
This is why you don't see those with some money and/or access to money (e.g. ex-Google ex-Facebook employees creating new startups) creating co-ops.
Likewise, examples of disappointed workers (e.g. tech layoffs, etc) who wished for a different corporate structure that gave them more ownership, are also not forming co-ops because they don't have the money. They're just trying to land the next job to pay the upcoming bills.
That's why the repeated advice and lectures to workers about "form co-ops" don't seem to make any progress. The reality is the workers just don't have the money.
