I don’t agree with pot legalization but I admire that Libertarians listen to their base, don’t bash them and use both political parties to advance their agenda.
The GOP does the opposit.
So your vision of Liberty tolerates (or even embraces) the notion of imprisoning an individual simply because they possess (or, God forbid, smoke) the wrong plant?
That's why both mainstream parties are an absolute joke with respect to Liberty: they simply argue about whose version of Tyranny should be imposed. The Constitution-trampling Drug War fascists have done more damage than most of the societal villains they decry.
The notion of someone's right to be left alone, to pursue happiness as they see fit, has been almost totally obliterated, and we are left with zealots on both sides of the fake political spectrum who must save everybody from themselves.
The average American has gone so far down this road of collectivist authoritarianism (and its associated Constitution-destroying consequences) that they have virtually no awareness of what real Freedom actually encompasses.
As long as someone is not committing crimes of force or fraud against another in furtherance of their bad habits, they have every right to make what others might perceive as bad choices, without having their freedom taken from them or their property confiscated.
