You have taken the Howey test, which defines what is a investment contract (and therefore requires SEC regulation), and replaced it with "if it's not securitized and its not tradeable it's not", which is, strictly as a matter of US law, completely and utterly wrong. The whole point of the Howey test is to focus on what the transaction does, not it's form, because it was trying to prevent people from tap-dancing around the regulation, exactly like what Coinbase is attempting to do here.
