@samtoland there have been some issues around retaining earnings for #workercoops, though there's been some creative work on that front recently. They're also used for worker co-ops that have undocumented immigrant member-owners.
Generally the #consumercoop statutes are a lot more developed in the States, so there really hasn't been perceived need to jerry-rig something on an llc structure for that model.
And #multistakeholdercoops are virtually nonexistent here, so hard to say on that front.
