The problem is what happens after you’ve established that ideal of using force to only ensure everyone maintains their basic rights. Without a way to prevent it from being co-opted, it inevitably becomes an even bigger evil. Now I’ve traded stepping out of my bunker and getting shot for my watch with having my bunker ransacked because I didn’t keep up on my monthly dues. Clearest example is every country that’s ever adopted communism, but you can even look at what happened to the American colonies immediately after forming a central government - higher taxes and stolen land (and I’m not talking about the Indians), not to mention what’s it’s become today.
