> That makes sense. Externalities will be less. I would love to hear how anarcho-syndicalists think that any remaining externalities can be managed without a state. Like, if I'm in a co-op with 10 people, I can still see us all deciding to screw over society just a little bit for our own gain, and telling ourselves a nice story that that's not what's happening.

States are here to stay and are, in fact, necessary for the enforcement and arbitration of business law. They're a necessary ingredient to any regulatory regime.

I look askance at any solution that pretends to completely "solve" the issue of externalities. Humans are optimizing, externalizing creatures, and our organizations will reflect that fact.

Given all that, though, an ecosystem of cooperatives actually does do a better job of policing and creatively regulating externalities in a manner more beneficial to society than many forms of government regulation.

This is because governments are susceptible to regulatory capture by private capital, and the concentration of wealth into relatively fewer hands only exacerbates this problem. Cooperatives actively fight against the unfair concentration of wealth, and an ecosystem of cooperatives forms a network of reinforcing relationships that find opportunity in waste that private capital firms might otherwise externalize to the public to deal with.

A good example might be the worker-owned retirement homes in northern Italy. Staff earn higher wages -- and care is consistently rated as far better -- than at either for-profit or public facilities.

> Don't both capital and entrepreneurship require asymmetric compensation for the unusual amount of risk of starting some ventures?

Sure, but that's not incompatible with cooperative ownership. There are forms of worker co-ops which give greater ownership stakes to workers who contribute more, take on early risk, or have seniority. It's not binary.

There are cooperatives that look indistinguishable from SV startups. The only major exception is that they grant voting stock to new hires instead of non-voting share options.

> Even if the playing field was levelled, why would a founder or investor willingly opt-in to a corporate form that will massively reduce their upside in the 10% chance that they end up succeeding?

Because the odds of a cooperative succeeding are higher than with LLCs and joint stock companies (see upthread and numerous studies). In other words, many people would be more willing to accept a 50% smaller slice of the pie if the odds of success triple.

Another minor point here: Cooperative structures also have an advantage in sustainable longevity. VC-funded companies are exit-oriented and tend to struggle to settle into enriching, viable companies post-exit. Cooperatives offer a competitive advantage to the entrepreneur who is not looking to pump-and-dump their life's work, but instead build a sustainable business in the long term. All things being equal, workers will overwhelmingly prefer to work at a mature firm for ownership than simply for wages.

> But what about the far more risky (both capital intensiveness and probability of success) ventures, e.g. starting a nuclear fusion company?

Interestingly, that's not too dissimilar from what Mondragón was at its inception -- a capital-intensive, high risk business. And there are actually lots of cooperatives that succeed at these margins around the world. They're just not easy to start in the US due to a blend of factors including culture, concentration of wealth, and hostile regulations.

But I'd like to point out that, even if the answer is "accept that co-ops can't service these particular high risk sectors properly due to a fundamentally inadequate incentives," nobody in the cooperative space is advocating the eradication of joint stock companies or other corporate forms. Cooperatives are not a one-size-fits-all solution. There will always be cases when LLCs, LLPs, JSCs, etc are a more appropriate form. We just want more choice.

I would strongly support a federal law defining a standard cooperative corporate form and giving worker cooperatives preferential treatment under the tax code. I think society could only benefit from such a change.

At worst, we'd see a bunch of new cooperatives pop up on the fringes, where they had previously been too onerous to start or operate. At best, we'd see a much more democratic economy across the board, with workers more invested in the success of their firms and firms more accountable to their workers.
