>You said that crypto is only useful as long as governments use it for nefarious purposes and money laundering — so basically it’s a guaranteed relevancy in the future, no? How is that inevitable uselessness?

It's hard to say how long those nefarious purposes will be tolerated. There may come a time when the governments of the world don't even have to pretend to not be doing nefarious shit. At that point, cryptocurrencies will only be a thorn in their side, and will be under heavy attack.
