It's only a problem so long as it's framed with the question of "should, and can the state fix X". If, however, you state it in state-free terms such as "is there anything wrong with an individual stranger potentially harming his/herself?" then the answer is pretty obvious. It's much harder to justify things against an individual without the state. E.g. "Those bums down the street repeatedly use drugs, and I think that will lead to them damaging my property / harming me. I'll go ahead and hire some security guards to prevent them from taking drugs, or beating them up if we find out they have drugs on them." Disclaimer: I'm an anarcho-capitalist.
