In theory, your reasoning is correct. However, practically, legalization of "hard" drugs will have it's consequences, one being that there will always be a percentage of the population that cannot control their addictive behaviors. Having a government infrastructure that caters to weaknesses with cash rewards, will in effect promote addiction.

But, this is solvable, as you've correctly pointed out. But do we have the will? Ending the WOD is going to be difficult do to the moneyed interests influencing both sides of the debate. Ending the welfare state will be 100 times as difficult.

That doesn't mean that we shouldn't try our damndest!

As if it doesn't have consequences now. Anyone who wants drugs can get them easily.

As now. Nothing changes in these regards.
