I hear what you&#x27;re saying and it makes sense. What would prevent such contracts from being a boon if we were all in one &#x27;country&#x27;(the world), though? Is it to hold onto something deemed of value that some may consider arbitrary (speaking a particular language, celebrating certain holidays)? Perhaps some of the values held in certain countries are the things folks want to hold on to (personal liberty vs group cohesion, gun rights, etc). We humans are sure interesting.
