All law making is a moral activity. All laws are an expression of some underlying moral imperative.
True. What’s that have to do with adults smoking pot?
This is the part that makes me reject libertarianism as a thoughtful philosophy. I believe in individual liberty, but don’t we have enough proof that permissive laws or legalization of what had once been immoral didn’t improve human life?
Prostitution legalization didn’t end the white slave trade or alter the mentality of pimps and prostitutes. Legal or illegal it still draws the same lost souls.
Hmm... I’m pretty sure when the Feds wanted to ban alcohol, it required a Constitutional amendment to do so. What makes marijuana any different?
They only work if the prevailing morality [such as it may be] supports them.
Once upon a time, there were laws against sodomy and adultery, because everyone -- or almost everyone -- supported them.
Morality cannot be legislated.
But to try and re-introduce such laws today would prove fruitless. Society, whether right or wrong, no longer supports them.
