The market is shaped by human aims. The laws we speak of were not handed down by aliens. They were specifically created by society for the benefit of society.

The market is shaped by human aims. The laws we speak of were not handed down by aliens. They were specifically created by society for the benefit of society. There is no such thing as a best possible world. Not two people would ever be able to agree what that even is. Every benefit comes with a detriment. It's just a matter of what tradeoffs do you want to accept. Society has made its choice, seeing a regulated market as being more important than access to drugs for all (for now; that choice is fluid and able to change in the future should society change its views, but trying to predict the future is well beyond this discussion).
