It's that category that the SEC appears uninterested in. Some ICOs (like Brave's) are tokens that entitle you to goods or services on the platform in the future. These are effectively currency scrip (or "gift cards" in the article's terminology), and the SEC seems to consider them outside its jurisdiction.
I suppose the only functional difference between ICOs and gems from clash of clans is that you can resell your tokens on a secondary market because of the decentralized nature of the system. But so what?? It's a solution to a problem that never existed.
If not, why buy them now?
If yes, doesn't that trigger the Howey test?
The interesting thing about ICOs in this category is that there's a potential secondary market, so if there turns out to be significant scarcity, the price may rise, but if not, it's worthless (other than for its intrinsic value). But this isn't all that different from GMail invites circa 2004.
