Cut a couple of wooden oblong pieces of solid wood. The thin side would slide easily up between the columns. The thicker side would wedge solidly between two columns. A hole in the center could have foot straps hanging from them.

Wedge, step up. Turn, slide up, wedge again, step up again with other foot. repeat.

Lol they are going to carry the wood with them the whole trip? They are going to carve them on site from wood they found in the Sonoran desert? There aren’t going to be border agents on the other side of the wall monitoring who is approaching the wall?
What ever the wall is it will be better than a wide open border and the fact that people can’t just walk across will mean less agents can do a better job on focusing on an idiot that thinks he can climb over with wood or rope or a ladder whatever. Additionally with less agents needed to watch the border the other agents can spend more time addressing those that fly into the country and overstay their visa, a win-win despite your Doom and gloom hyteria that they will be whittling slats to climb over.

Any barrier needs observation to be effective.

Good grief! A simple 'barrel' crown on top defeats that.
