And now what is a border, is it something that restricts the beliefs, thoughts and membership of a group of people by simply being painted on the ground, or is it something that is defined around such a group dynamically.

At the simplistic level, borders = taxes = infrastructure, so if you're part of the group you pay the taxes and have access to the infrastructure.

Whether they are legal or not, laws are relative and Arnie could, at the stroke of a pen, make them all legal. Yeah a few people might be unhappy and revolt, but then they are the ones that would be sent to jail for doing illegal things during their protests.....

So, then, is an increasing amount and complexity of technology something to wish for when we can't even get along with our sticks and stones?
