Hold on hold on. You previously blamed our current corporate system for preventing workers from owning their means of production.
Uber exemplifies the vision you seek... where individual workers own their own means of production. There is no need for a worker coop for drivers. A driver uses one car -- their own. They do not need to own some large capital investment (it's not like the owners need a factory to work). Why should driver A and B share cars together? That's the very vision of shareholding that you deride.
Uber, the company, is obviously not a worker coop, but frankly, its model is the most viable way towards a vision of worker-owned businesses. If you truly desire worker coops, instead of large corporations, then the vision of uber and the system it seeks to achieve ought to be lauded, even if the specifics of uber's implementations should be scorned.
Unfortunately, all the progressive labor activists made such small worker coops illegal. A more sensible solution would have been add a corporate structure that lets drivers band together for certain collectively purchased services (like health insurance and other benefits), without all the reporting requirements of normal corporations. Instead, they basically banned small businesses.
