I wonder at what point the up-front costs of massive desalination would overcome the (often hidden and externalized) costs of projects like this.
As long as we don't try to hide and externalize the cost of all the hyper-saline brine management that comes with desalination.
I don’t think the brine pollutant issue has been meaningfully solved. You are also now pumping water inland uphill the whole way.

Desalination is dominated by operating costs.
