> WSGR is claiming that once tokens are used primarily for commerce, the value will be determined by commercial usage
And they're wrong. If a token is primarily used for commerce then it's value might come primarily from that usage, or it might not. But it certainly isn't some sort of get-out-of-jail-free card.
I don't see how you're disagreeing with WSGR here. You seem to be saying that even after a token becomes broadly useful in its intended setting (say, storing files), it might still get most of its economic value from speculation. WSGR agrees, and seems to go out of its way to say that coins would likely remain securities under those conditions.
