That depends on your values. I think it's bureaucratic BS in every country. The world hasn't been like this forever, and still isn't like this for other animals.

People didn't receive handouts from governments in centuries past for just showing up and performing no contributory function. Kill all entitlements and let's open em' back up!

What reality are you living in where countless animal species aren't territorial? This is common sense.
That would be amazing if some country tried to enforce visa rules on animals.
Humans and animals enforce their borders since millennia.
The idea that borders are unimportant is very very recent. That is to say, its commie gobbledygook.
If you enter a bear's den, especially if it has cubs, the bear will likely attack you.
If you enter the territory of a swan, especially during nesting season, the swan might attack you.
If a foreign object enters some animal's body, the immune system may attack that object.[0] Allergy might be related to the immune system misidentifying allergens.
Squirrels can be surprisingly territorial.
Ants have wars. [1]
This is not surprising, since the consequences of territory being compromised can be severe. For instance, in this case [2], the territory was compromised through deception, like pretending to be one of them, and it led to the severe weakening or death of the whole colony through the mass devouring of their offspring.
