If I just start building the infra for a worker owned tech co-op
maybe clients and workers will just appear like that baseball
ghost movie.

I guess the serious thing to do would be to research how you
setup a legal entity and a name. I sorta researched it to get
an LLC, but the group way was the hard part [0], where you
choose to have the primaries be change-able.

[0]: I just chose the easy setup for the LLC I did.
