Te Wall is metaphor for actually enforcing the border.
This^^^^^
It's not so much the wall as it is the enforcement of the law. the law that says if you want to come to America there are rules you must follow. If The Donald can do that, then a huge expensive wall is probably not needed.
My bet is the guys along the border are so tired of a non effective federal government they have resigned themselves to forever having to deal with trespassers and thieve on their land and factor it in to the high cost of doing business.
