It appears to me, Salmo, that what the "law" does is provide a means to hold some accountability for the lawless who would otherwise continue mayhem without consequence.
The effectiveness of jail time can be a deterrent after one expends enough of their life behind bars, I suppose. Monetary punishment is selective in its impact.....hurting the poor much more than the rich, but time behind bars provides an equal (or nearly so) learning experience.
You can't really believe that we don't need police to counteract survival of the fittest.
Good grief Slab; don't go being as dumb as KK says you are. Of course laws hold the lawless accountable. But why does growing, manufacturing, distributing, selling, possessing, or using drugs have to be a behavior for which there needs to be an accounting? You can legally drink yourself sh!tfaced, and society doesn't need you to account or face any adverse consequence UNLESS you behave in a way that poses a danger to society, like driving a car and hitting someone.
Now be smart and stay with me here a second while we reason with logic and not empty-headed emotion. Society is obliged to protect itself from actions by its members that are harmful to it (society) not the members engaging in actions that you may disapprove of. Society is not harmed by members who engage in the aforementioned - growing, manufacturing, distributing, selling, possessing, or using drugs. Society is only harmed when one of its idiot members decides to perform an action like DUI or shooting a competing drug seller, etc.
By legalizing drugs, all drugs, most of the actions that actually harm society become less likely to occur.
OK, are ya' following? I've demonstrated that roughly the same proportion of society that uses drugs when they are illegal will use drugs if they are legal. And hopefully you understand that it is socially stupid and pointless to hold people "accountable" (in your words) when their actions do not harm society, even if those people do harm themselves ( you are at least that much of a libertarian, aren't you?)
What society does need to hold people accountable for are actions that are actually harmful to the non-partaking members of society. And since numerous laws already cover that, nothing further is necessary.
No where have I suggested anarchy or survival of the fittest, sans police. Of course we need police, and it is the job of police to protect us (to the very limited degree they can) from those who perform actions that actually harm us. That institution is known as civilization.
Nonetheless, putting people in jail or imposing monetary fines for behaviors that are of little or no consequence to the rest of society is flat out stupid, not to mention costly, unproductive, and in the case of the war on drugs, counter-productive. If you do not understand this, I can only surmise that you are dumber than a box of rocks and that what KK says about you is pretty much spot on.
