It's not like drugs or porn. They're fun and they address desires that are as old as our DNA.

Bitcoin's selling point is its utility. Take away the ability to openly utilise it in said country and who is going to put money into something they can't spend and others won't want or accept?

I'm not gonna think 'goddamn it that sounds desirable.' I'm gonna think 'Fuck that.'

Sure, there's black markets, hiding money, transferring it across borders but that's relatively niche. If BTC was made effectively useless tomorrow I struggle to see how that's going to turn people on. There are plenty of other options for them.
