This "I don't see a use-case for my very limited life/experience/work" is very toxic.

I use Bitcoin to get paid and to pay. That is legitimate. I know a lot of people that uses it for the same reason. There is also a whole lot people using it to evade capital controls; which is modern day repression on freedoms.

Also what is wrong about buying "drugs"? Would you say the same about an encrypted messaging platform that operates in China. That the user should not use it since China did not approve that?
