I actually dont mind securities for tangible thing like weed. The shares represent the value of the assets held by a company where tokens may just used as terms of exchange. For tangible goods and physical things, securities have a place, for online platforms and software, crypto has a place. Best not to be to bias toward stocks as they are a suitable ledger for specific business models. I do agree that a token is a much more sound form of investment but you could make an argument for physical goods like weed.
