The difference being reality and utopian fantasy.

It's like people who say equality is best today despite the very real and present need for equity.

They're very real and perfectly fine concepts on paper. But it's a massive difference between how it translates to reality on paper and how it actually manifests when filtered through the human condition.

Kinda like Libertarianism. Trickle down economics. Live and let live. Personal freedoms. Communism.

Turns out reality isn't so easily fit in such neat little boxes to cover the gamut of how every human acts and reacts.
