It is also a fantasy to believe that the general population is currently responsible enough to exist without a government when they are so easily manipulated/brainwashed by psychopaths.
Another fantasy is that you’re going to send them to “libertarian reeducation camp” to change their social structure and beliefs. Or that you’re going to change everything by getting the State out of education.
This is a lot more complicated of a situation than there just being someone officially in charge.
Step outside of your head and look at the big picture and the true state of humanity, not everyone is as smart or principled as you. Nor do they necessarily want to be.
