That is putting the cart before the horse. The USA is not a libertarian government. Why did anyone think that it was a good idea to invest in products that would only survive in a libertarian government?
I think investing in crypto is purely based on greater fool theory.
Doesn't mean there aren't any legitimate uses for cryptocurrency, let alone the blockchain technology.
In this sense, why should Coinbase and a currency exchange booth in some airport be considered any different? Of course, Coinbase doesn't quite operate statelessly like that, and to me that's the issue here.
