Sure.

The ability I have to leave my house and walk around is of a different quality to the ability I have to go to the supermarket and buy some food. Positive vs negative rights, something like that. I'm feeling lazy in my explanation but probably you know it already. :)

With drug abuse I feel it's quite simple. If you want to do meth in your home, I think you're a bit daft but I'm mostly happy for you.

If you end up in a tent city under a bridge abusing passers by and committing crimes to get your next hit, well, we should punish that hard.
