Given your very clear and strong stance that this is something you won't ever try, of which I don't have any issue with, I won't spend a lot of time debating this statement.
But, your analogy with getting a lobotomy to enjoy life being even remotely equivalent to doing psychedelics is simply wrong. The effects are not similar. You are also drastically overestimating the gambling nature of psychedelics.
You're probably way more likely to wreck your life while drinking alcohol than you are with psychedelics.
