Building a physical wall is silly and impractical, obviously.
IF you oppose illegal immigration, the way to fight it is the way most Republicans would never accept: by coming down hard on employers who hire them.
If TrumpCo or whatever builds it, I’d imagine one could huff and puff and blow it down pretty easily.
This wall will be SO tall that you will pass out of oxygen deprivation before getting to the top!
Me or Trump? Cause I’d like to think I’m in pretty good shape.
You know, if those ‘Tough Mudder’ races become an Olympic sport one day all the people who climbed the wall would do great.
So. I’m having a retaining wall built on my property today. It will be about 30 feet long, and about 5 feet high. The landscaping company is pretty much all Hispanic. At the end of the project maybe I should ask the crew if they can climb the wall, just for a photo op.
Of course, I’m not as good a negotiator as Trump, so I can’t get them to pay for it. I’m actually paying them!!
You should tell them they have to pay for it! 
The wall that he is currently building will take years to climb over.
Because it’s YUUUUUGE!
Of course, anyone could just fly a drone over, no problem. So there’s that.

So you have the guys with the guns there. Why not save money and not bother with a wall? If you must have a barrier, why not barbed wire fence or something?
Bolding Mine…
Darn it…I read this as Laser wall, and thought you had some cool effect in mind. Now I’m picturing that invisible wall at the beginning of The Running Man “Border Deactivated…Border Deactivated” and then someone’s head blowing up.
Or the more tame wall from Lost
I do not know what they are, and neither does Wikipedia. Link?
It occurs to me that if the desert is fairly tough to cross, you don’t need much of a wall. Just something that a car or horse can’t get past. So, people can drive up to the wall in a jeep, dig underneath it in 3 minutes, then they must cross the rest of the desert on foot.
This is a bollard fence. Really designed more to keep vehicles or horses from crossing, not necessarily people. Although if you position each bollard close enough to it’s neighbor, it can do that as well. Prohibitively expensive, for the application in question.
A good story on what is good about a bollard fence can be read here.
Cheers.
If you want to discourage pedestrian desert crossings, you’ll have to get those pesky humanitarian groups to stop installing water stations.
Maybe replace them with automatic sentry guns instead.
Who’s in favor of it?
How YUUUUGE? Drones can only legally fly to 400’. 
You’ve never heard of anyone being in favor of open borders?
Wouldn’t open borders negate the illegal part?
Yeah, I’m thinking the Iron Curtain in Europe was manned with military grade machine guns and anyone seen in no-man’s-land would be quickly dead.
Let’s not forget the friend of every sealed border – the land mine.
