You're right. Those all have 2000 mile walls through total wilderness and along property lines and rivers. It's exactly the same. I was wrong.

It's not like anyone could use a ladder, ropes, dig a tunnel, or fly drones over it. And I'm not even trying to think of more clever ideas. 

But that's not even really the point I was talking about. I used it as an example of simplistic fear-based thinking and you showed exactly the depth of consideration you've put into policies like this. 

They are waste of time and resources and will not fix the problem. But the problems will carry out in different ways over the course of years which will allow people to keep the finger pointing narrative going, asking for more resources and more power until the world looks nothing like it is today and the problems we're trying to solve still aren't solved.

In fact we might not even remember what we're trying to fix but you'll still be on guard against whatever boogeyman group they decide it is next.
