The context of the quote: > I don’t welcome a currency that’s so useful to kidnappers and extortionists and so forth... So, I think I should say modestly that the whole damn development is disgusting and contrary to the interest of civilization. I find it strange to criticize an asset for how it gets used in extremis. I feel like the same criticism could be levied against the dollar.
For any thing that has both positive uses and negative uses, it seems reasonable to weigh the positives against the negatives. The dollar has substantial non-infringing uses that benefit people. Bitcoin less so, and particularly when weighed against the great harms (environmental or criminal) that Bitcoin brings, I don’t find the criticism baseless.
If you're trying to ban cash because you can buy illegal things with it, then you have a logic problem.
