I find that the policies built on “logic only” tend to break down because they ignore emotion and feelings entirely. People are emotional by nature and our feelings, sense of well-being, sense of justice, sense of oppression, and so on are very real in that they drive how we react and respond to each other. Trying to make a utopia based on people not reacting to their emotions is like trying to make a utopia where people don’t need to eat - it might be nice, but it’s unrealistic.

Imagine if someone came up and kept stabbing you with a rusty pin every day, and whenever you jump away and say “ow!” they roll their eyes and say “logically, this shouldn’t bother you, because it only hurts for a second, you’re not bleeding and I know that this pin won’t give you tetanus. You’re being very irrational right now.” Based on their logic, they’re right, you won’t be measurably hurt, but it still has a real effect on you and you’ll want to do everything you can to stop getting randomly stabbed by a rusty pin every day. Your lived experience is real to you.
