My optimism could totally be misplaced! But here's an excerpt from the SEC statement that seems to go beyond your "security or commodity" classification.
> A key question for all ICO market participants: “Is the coin or token a security?” As securities law practitioners know well, the answer depends on the facts. For example, a token that represents a participation interest in a book-of-the-month club may not implicate our securities laws, and may well be an efficient way for the club’s operators to fund the future acquisition of books and facilitate the distribution of those books to token holders.
It becomes a lot easier when you realize money isn't real, it's a constraint. Like oxygen, it only matters when you don't have it --- once you do, it becomes irrelevant -- a story that allows you to represent incentives to do positive deeds.
Gotta love the unlimited supply of optimism in the cryptocurrency world. Every single existing token is either a security or a commodity, but people still think they can squeeze through the "utility token" loophole.
