People are just as capable of escaping into fantasy worlds without drugs as they are with them (to turn your bit about epiphanies against you). It is down to the character of the person, whether they will use these things to enhance their relationship with the world around them, or use them to create a cocoon within which to hide away from perceived "evils". I don't think you'd call the ancient Greeks, Egyptians, Babylonians, Indians, Aztecs, or Maya (to name a few...) "escapists" in their attempts to connect to a greater, deeper, more intense reality than the one available to our crude physical senses.
As things stand, I could well be one of those "psychonaut hippy dipshits" to you, and I fucking love this world, for all of the beauty and horror contained within it. Not one thing is unappreciable; psychedelics have proven to me what conjecture already suggested.
