Since there is already some sort of wall in some places.
What's wrong with building a new one that actually works?
After all, it will increase national security, create jobs, stop illegal immigration of all kinds regardless of race, stop human sex trafficking and a lot of drug smuggling as well.
Some people say it can't be done. I'd like to hear why it can't be.

It is going to cost a lot of money. Like a stupid ton of money. It will need to be constantly manned and patrolled. Which is going to take a lot of manpower and technology.
Oh and assuming we can do all of that there is no guarantee the thing will actually work. It's not like this is going to be a force barrier that is impregnable. Sadly walls and obstacles are made to be overcome and they often are.
And what does it gain us. More secure borders? A wall isn't really going to keep out a modern military. Most weapons will be able to decimate them pretty easily especially if the wall is just sitting there.
Stop illegal immigration. Only if the wall actually works.
Stop illegal drug trafficking and the sex trade. Maybe but there are other means of entering the country with these things like planes and boats. Plus there are probably more cost effective ways to handle those problems. And the success of the wall once again hinges on it's ability to keep people out which will be an unknown factor.
I don't actually have any problem with the wall- it certainly isn't unethical.
Mexico ain't ****ing paying for it though.

People get through the fences now, so Southern immigrants will just make new passages and get through, since it would be nigh impossible to patrol 2,000+ miles of fencing/wall.
So we'd have a barrier that cost a ridiculous amount to build, costs a ridiculous amount of money to maintain and patrol and immigrants would still be getting in.
If a wall is going to be built Trump might as well go Mega-City One with it and build it around the entirety of the contiguous United States. Alaska, Hawaii, and the U.S. territories can fend for themselves. They can be the Cursed Earth.

'I would build a great wall, and nobody builds walls better than me, believe me, and I'll build them very inexpensively — I will build a great, great wall on our northern, eastern, southern and western borders. And I will have Canada, the Atlantic ocean, Mexico and the Pacific ocean pay for those walls. Mark my words.' -Trump
Your question was silly and not comparable; it's purpose was to troll. We have statistics that show how gun control can work and we have miles of data showing that man-made/effected climate change is a thing.
While the logistics of said wall show it's both futile and nigh impossible in the current climate. We also have China's Great Wall as an example, it didn't work; the Mongols invaded.
