Isn't it an investment? It's basically private equity/venture capital.
I certainly see your point, I do. Here in CA, these marijuana "corporations" and holding companies are popping up everywhere, and they're doing public investment offerings just like the one in that link I pasted. Sure they're not publicly-traded like GM, but since marijuana is legal by the state but not Fed, would anyone do anything with the consumer relationship if, say, a consumer wired $120000 to that holding entity? The initial investment funds are legit customer savings.
Where I'm coming from is this -- I don't care what you invest your money in to make money, but what do we do with the relationship once our customers start getting "investment income" from the holding entity, with us knowing exactly what that holding entity is and where its business is being derived?
