If it works, even a little bit, I'm all for it. There are similar stories about e.g. China restoring vast arid lands back into green lands through simple measures that basically include a little bit of engineering but mostly letting nature do what it does best. Similarly, Northern Africa is basically turning land into deserts by letting goats and sheep roam free and to eat everything that looks even remotely green. Some simple fences keeping the animals out can apparently restore a lot of that land in years thus making it possible to farm all sorts of stuff that previously would not grow there at all.

This suggests that figuring out how to manipulate nature to function more optimally, can actually be beneficial. Even merely stopping to do things that are clearly misguided seems to help. Healthy soil does all sorts of things that are beneficial. Holding carbon is part of that yes. But it also holds water. Without water nothing grows. If you fix that, bio diversity increases, the soil becomes richer, more stuff grows. Including the stuff we're interested in farming.

Much of last century was dedicated to intensive farming and short term yields without any regard whatsoever to the long term impact. None of that has to be permanent. If you read science fiction, a popular topic is terra forming. We'll have an opportunity to terra form earth long before we need to terra form somewhere else. Might be easier too and feasible.
