the Welfare State needs to go first. [...] Because if you switch #1 and #2 around, you will achieve the new #1 (legal drugs) but you will abandon all hope of ever getting the new #2 (ending Welfare).
Nonsense - those people who before legalization were responsible enough to avoid marijuana use because it was illegal, will after legalization remain responsible enough to not use themselves into welfare dependency.
And since alcohol dependency is several times more prevalent than marijuana dependency, if legality means no end to welfare then that goal is dead already.
I figured out the Libertarians a long time ago. You have no interest in ending the Welfare State. You all just want to party.
