Your comment on other countries having different laws is a bit strange too. Are you arguing for a universal acceptance of the same laws, that instead of being based on societal and cultural norms, that it is an human principle that cannot be violated? So...... yeah I am a bit confused here.
I'm going to pick out this question to respond to because I can hit all your other points along the way. Call it a one-argument-fits-all arrangement.
I started this whole discussion out, way back on page 1, arguing it as a basic human principle that cannot be violated, and I remain firm on that point. How many times have I repeated the phrase "inalienable human right" in this thread? Too many, I'm sure, but it's a very deeply held conviction.
I prefer this argument in the abstract, because I'm an idealist, and an absolutist, and that's how I think and how I prefer to argue, but we've led each other on this 3-page journey to a lot of other places and I've gone along with that for argument's sake. I've argued it in the abstract and in the practical. Now, though, if you're asking for a firm stance from me, I'll go ahead and make it and sum up my argument and then give you the last word to do the same because otherwise we could be back and forth on this for months, right?
I look at it this way. There's two ways to view the question of human freedom: either we're born as totally free beings with everything permitted, and then we begin to subtract what's permitted as necessity dictates... or we're born as totally inhibited beings with nothing permitted, and we begin to add what's permitted as necessity dictates.
For example, I believe the former... that we're born totally free with everything permitted. Now, we start to remove what's permitted as necessity dictates. No rational, reasonable human being would argue that murder should be permitted, so we subtract that. No rational, reasonable human being would argue that rape should be permitted, so we subtract that. Theft, destruction of others' property, etc etc. We subtract everything that's completely indefensible. However, something like we're discussing here... drug use. A rational, reasonable human being such as myself can argue that it should be permitted, and a rational, reasonable human being such as yourself can argue that it shouldn't. Given the fact that we've established doubt on the subject, my philosophy of the innately free individual demands that we give the individual the benefit of the doubt and permit it.
Someone else, on the other hand, might argue that we're born absolutely inhibited, and freedoms are added as necessity dictates. No rational, reasonable human would argue that a person shouldn't be free to choose their own occupation, so we grant them that. We grant them every freedom that no one would argue against. However, on a topic like drug use where an argument can be made either way, the individual defaults to inhibited and so he remains in the presence of doubt.
See what I'm getting at here? In my view, once you remove those things that absolutely must NOT be freedoms, what you're left with is the most free individual you can possibly, conceivably have, and that becomes the default. Any further removal of freedom from that individual is a grievous affront not only to him, but to all of us, because the denial of a basic, inalienable right to any individual diminishes us all.
You can keep your practicality, you can keep your what-ifs, your supposed victims... none of it enters into it. Unless another innocent party is directly harmed by an act... not just potentially, but directly harmed, then it's not only permissible, but an absolutely vital right, necessary for the wholeness of the individual.
I'll give you the last word.
