What would you say is the best example of a concrete, real-world use case for one of those tokens that would refute the article's claim that blockchains are “a solution in search of a problem”?
I ask because a lot of these things (exchanging one USD-pegged token for another, borrowing a token for another token) seem like problems that wouldn't exist to begin with, without blockchains.
