ANY governing body is concerning. You either have clerks, doctors or religious people deciding who can take psychs, and these are equally bad.
Regardless of your friend's experience with the government, I guess from the first part of your message that you do understand that the ban on psychedelics was put in place to suppress the left-wing, anti-war hippie movement in the cold war era. Let's not perpetuate the unjust stigma on hippie culture.
Yes, when we're in the future writing some official paper for the government outlining a system for legalizing psychedelics, I'm all for using professional language. But don't stigmatize our heritage "in the wild". The human rights movements of the XX. century didn't win by assimilating majority prejudice, but by attacking it.
I want Hippie Pride marches with people wearing tie-dyed hoodies, shaggy hair and marijuana leaf badges, not doctors in suits and white coats in high-rise buildings talking clinical language down at people and making millions off patentable analogs of ancient psychedelics.
Nobody is against regulation. But you regulate the supply side, not the demand side.
We ARE "the population at large". 
The question is, whether most people need to go through the black market to have access, or the black market is a fringe.
