The feds will still go after it as an illegal drug when presented as recreational and the will keep the stigma going on forever. Furthermore it will keep a lot of talented people out of good job opportunities for smoking a joint after work instead of having a glass of wine.
A better job at what, getting you high? Pretty sure they already have that, and while it doesn’t net them 10k per dose the Sacklers would have liked that very much no doubt.
A better job at treating a range of physical and mental health issues. Recreation is just a bonus.
