But not value that can be captured by the creator of the protocol. Let's go back to cloud storage. Sellers of storage sell 1GB-Month for 1 token (or whatever). Buyers of storage eventually run out of tokens because they've given them all to sellers. So they have to purchase the tokens back from sellers for dollars. How much will sellers charge? The cost of storage (plus whatever profit they can get away with).
At that point buyers of storage are paying exactly what they'd pay for storage if the token system didn't exist. It's just this goofy middle layer of scrip. There's no magical extra money that the protocol creator can siphon off.
Step back and look at the big picture. The only way for a protocol creator to make money is for either sellers of storage to charge less than they otherwise would or for buyers of storage to pay more. Why would either of those two groups ever want to do that?
