You are tying yourself into knots, Guano. Look: Morality and law are NOT THE SAME. Repeat after me. They are NOT THE SAME.
That means that we can divide actions into a sort of venn diagram:
<center>
<table>
<tr width = 70%><td width = 70%>Legal and ethical(ly neutral) actions
<td>Legal and unethical actions
<tr><td>Illegal and ethical(ly neutral) actions
<td>Illegal and unethical actions
</table></center>
Laws are a matter of definition and are easy to look up. But since they are NOT THE SAME THING AS ETHICS, that STILL leaves people responsible to make ethical judgements. (Translation: Sorry, you can’t let other people do your thinking for you.)
Apparently the ethical problem you have with pot smoking resides wholly in the fact that it’s illegal. (The rest seems to hinge on whether or not it’s a waste of time, which is not much of an ethical issue. If it were, masturbation or posting to the SDMB would be unethical.)
But is it unethical in and of itself, if you do not consider the laws? Is the actual act of lighting up a joint - say in Holland - an attack on one’s neighbour, a theft of rightfully held property, a denial of someone’s rights? How could it possibly be?
So, besides your arbitrary “law=morality” prejudice, pot smoking is ethical, or at least ethically neutral. That would put it in the box in the lower left-hand corner of the diagram.
We do not have an obligation to ourselves or to other people to behave legally. We have an obligation to ourselves and to other people to behave ETHICALLY. Repeat after me. You have to behave ETHICALLY, to which laws are fundamentally irrelevant. We would still have to behave ethically if we were living in an anarchistic commune with no laws.
As everyone knows, the state requires us to behave in concord with its laws, non-compliance with which may be punished in various ways. But that is NOT AN ETHICAL QUESTION, that is a question of political science and sociology.
You’ve made it to the bottom. Now go to the top of the post and re-read.
Now do it again. (I want to make sure you are reading this.)
Now, for Goddess’ sake, we’ve explained this to you fifteen times if we’ve explained it once. I’ve drawn you a freaking picture. Can’t you come up with any other kind of argument than banging on the wall and repeating yourself, wailing?
