Isn't this just saying "something can't be a pyramid scheme unless it has already collapsed"?
Whereas the argument being made is that looking like a pyramid scheme is something that tells you something about the future likelihood of collapse.
(I think there's also an interesting dynamic that's not explored much here about "finite supply" - unless/until every coin except for one or a small handful collapse, it seems like "crypto" as a whole is subject to inflationary pressure from new coins. Would BTC be worth more in USD terms if ETH didn't exist?)
