It would need to be a worker owned co-op.
Empowering people to do the impossible
Collecting the knowledge needed to bootstrap a solar punk civilization even in the face of collapse
This is the obvious way, yes. But it can be also a customer-owned one (housing co-op), or mixed / multistakeholder (patient/doctor-owned medical service co-op). We are not constrained by XIXth-Century imagination. :-)
Thanks for the names of other methods of owning businesses, we weren't aware of their names!
Keep in mind that, depending on local legal system, a co-op may not need to be registered as such. In Poland, for example, social enterprises can assume various legal forms, my favourite beng a civic association.
That's interesting, thank you!
In terms of legal structures, look to see if your local jurisdiction has a social benefit or public benefit corporation that you can legally register as. They're like an LLC, but place a social mandate of some kind above profit making. This is legally built into the charter of the business, meaning it can be enforced in the courts if later on the business attempts to violate that mission. It also allows such businesses to qualify for certain grants.
