Isn’t the biggest problem of desalination where and how to get rid of the brine safely, rather than the desalination itself?

No, that is a problem but not the biggest. The biggest is energy cost. And in reality brine is just watered down salt, just dry it some more and you have something more to sell

The trick is more that brine corrodes and clogs leading to high maintenance costs. But if needed it's solveable.
