>Isn't that why we don't have just a single country with a single set of laws?

Historically this is not the reason. And as a justification for continuing to have many countries it would only be convincing if people were free to choose which "experiment" to join or start.

The reality is, we are all guinea pigs that get thrown into some random country where some experiment has already started and we have no right opt out. If this is indeed someone's experiment, I would say it's highly unethical :)
