I think their point is criminals are bad, so anything they use is also bad. Like guns, and drugs, and cars, and food, and beds, and houses, and air. All bad. We shouldn't use those things, and we should ban them at the earliest opportunity.

I agree with you. Comments like that have such a low intellectual effort that they are mainly noise.

People in stable countries (us, uk, western Europe) don't understand the lack of confidence that citizens of underdeveloped countries have in their own government and financial institutions.

The argument that criminals also use ordinary money doesn't work here. Crypto was adopted by them at first, e.g. look at Silk Road, or billion volume hacks of exchanges. If BTC will grow then their relative power will grow.

And you could use this exact argument against the Turkish government banning crypto to protect its own exploitative currency scheme..
