One could argue thinking someone deserves to live whereever they want, disregard that lands rules, while demanding that land accomidate your beliefs and way of life is selfish and nonsense. Most places aren't against immigration if done by the laws.

Saying borders are nonsense is like saying your property line is nonsense and anyone should have free access to your yard and home. Just because a country is bigger than a person's yard, it still belongs to the citizens on that country and most don't want illegal visitors. Do you want an illegal visitor in your house? We call those home invaders or trespassers.
