That is both a cynical take and an anachronistic one. Sure you can argue that currently it is only used for get rich quick schemes. But to argue that it was get rich quick schemes from the start is innecessary. Also while get rich quick schemes are a problem with crypto, and there are crypto securities that evade regulation, there's also tax evasion, cybersecurity ransomware payments, drug trade, and not an insignificant amount of real legitimate transactions. You can again argue that the real transactions serve to pool illegitimate usecases with legitimate ones, like an xkcd mirror on the Tor network. But that would be a more nuanced and accurate take.
