What makes you think we can recreate on EOS a better justice system than the one we have in the real world?

What makes you think we would be better off without a justice system? It's not like everything is always bad with existing justice systems and there is no upside to them. All systems are imperfect, especially where humans are involved, but some problems cannot be solved without human intervention. It doesn't mean we shouldn't try. I mean the argument that we should not do anything legacy systems do, just because we might fail to improve them, is wrong in my opinion.
