Not every human experience is supposed to be based on performance, the moment you get away with performance as the utmost objective you will find some freedom.
LSD and other psychedelics give you insights, ways to see things without the noise of your ego always in front of it, and those experiences are valuable to oneself, not necessarily to be more productive, more creative, etc. Many artists used LSD, many other artists are teetotalers, each one has their own experiences to draw from to create their art, it's the sum of the self experience that creates impactful work.
You are looking at this as if life is some sort of competitive sport and people are only trying to gain an edge by taking mind-altering substances, that's not how life works nor a good way to approach those substances. You can't min-max life, as much as you try, that's the illusion of control living in your mind speaking.
