You have a very twisted way to see the world. If NK is more sovereign than most countries why should countries aim for sovereignty?

The bottom line is that the "paper treaties" allowed the world to function and create economic growth/trade not a sovereignty dogma. I think the total sovereignty dogma didn't exist even in the medieval times. Its roots are rather religious. I'm not sure where you want to go with that. Certainly not towards prosperity.

You don't want international treaties with nations you can't invade or what's exactly the gist of it?

Being a super power has benefits. That doesn't mean you can break economic treaties without consequences or that you can invade countries every time you don't like their economic policy. Bad behaviour brings reputational damage. Wars are costly(economic and politically). Soon enough you may find yourself alone and that you are not a super power anymore(i.e Russia).

Being a small country like NK or the UK you can play ball with the system or become poor. If you want to change the system you must be a super power and/or have powerful friends(i.e not sovereign)
