Also being at a worker coop doesn’t mean you have to sit in company meetings all day. For large organizations like Mondragon workers vote for representatives in an assembly, which then appoints a general manager.

Also also, an owner who cares is a single point of failure/leverage. If they fall on hard times personally or just want to retire, they can decide to sell the business out from under workers to a venture capital firm, or just to another business with a less benevolent owner.
