Either poor(ish) people trying to get rich, or rich people trying to get richer.
Whether that is good or bad is a different question.
(Yes, crypto can be regulated. Of course it can. The point is that it will continue to exist irrespective of regulation.)
"Of course, you can regulate it away."
The use cases for it I see are:
1. Cheaply send large payments without having to pay a bank fee (instead you pay btc fees plus conversion to and from fiat fees).
2. Anonymously transfer money if using a washing service (illegal to offer one in the US) or if you spend rawly mined coins.
IMO, crypto is a US gov invention that was pushed to speculative theater to give threat actors huge incentive to break sha256/512 publically, as the best use of such tech atm is to steal massive amounts of money. It therefore acts as a canary for when someone finally does figure out how to crack it or easily solve prime factorization.

Gold would be worth much less than it actually is if people weren't using it to store money. It is easier to store bitcoin than to store gold. (E.g., bitcoin is easier to hide from thieves than gold is.)
Any sufficiently large state actor can simply buy a zero day exploit to try and remotely get into a target computer and then steal the pk of the wallet. There are mitigation techniques such as multiparty signing and hardware based keys/wallets, but nothing is perfect. And the most secured active users of it are likely already on gov radar.
When physical currency used to be backed by gold reserves, then it could be argued that gold itself has material value, but nowadays it's all fairy dust[1].
To me, store of value commodities are interesting when unpegged from a mainstream currency in that they provide no dividends. Their ownly roi is via speculation of the masses. Castles in the skies. That is where I have a hard time underatanding the value preposition of crypto.
