…m seemed to be to harmonize border enforcement with existing laws in a way that benefited everyone. But as the borders became less porous, migrants began seeking border crossings that were more dangerous. Often these were in the high desert where risk of injury and death was higher. As the cost of crossing the border back and forth increased, migrants were less likely to engage in cyclical migration and instead stayed in the United States, either sending money home to Mexico or bringing their families with them.

This is a great point. But as you allude, unless American citizens will not punish politicians with ‘no reelection’ in response to support for a return to porous borders and M visas — not Green Cards — for short-term work by Mexicans, a return to less porous borders seems highly unlikely.
A priori and until implemented and latent issues materialize, it would seem less porous borders, M-visas (six months of work, with a six-month wait from timing of return to Mexico for a new application perhaps), turning back of those caught, and goings back and forth by Mexican migrants might be better solutions than walls, more enforcement, and detentions.
