I didn’t say they exist. Though Sweden was making an attempt (before their president was assassinated in the 1970s) simply by giving employee unions more power. If worker/employee owned co ops had more opportunities for startup funding, why wouldn’t they form organically and compete with traditional businesses?

There are non capitalistic economic systems that are also don’t require state ownership and are non authoritarian. Literally just incentivizing worker owned coops is an example of how you can drastically shift the economic system without changing the political system. Markets =/= capitalism. The ability to hoard capital and thus power through private ownership is capitalism. I’m not saying that what i described is the perfect system, it’s just an example of something possible outside of your argument.
