It appears we would have to become several magnitudes more repressive than Iran or China to accomplish that.
If it comes down to a choice between liberty or social order, I will choose Liberty and rely on my guns and guts to survive the social chaos that may (or may not) ensue. Others will choose 'a little temporary safety' in exchange for the chains of tyranny.
I hardly call banning a hazardous and crime provoking substance "tyranny".
But, if you insist, lets just do away with all laws that regulate behavior (and they ALL do) and just have anarchy. Lots and lots of liberty for everyone!!!! But no safety for any but the richest and the most heavily armed.
The question is not if we will have laws that regulate private behavior, we will, the question is, Where is the line.
