I suppose if there are anhydrous deposits of minerals
somewhere, perhaps in deserts, this could be done

You're proposing that we give up a huge area of land to create an ocean to keep us from losing huge areas of land from the encroaching ocean. |

However, if all you're doing is hydrating minerals
there would be less loss of land. You could irrigate
bits of desert below sea level with it as well, and
increase fertility. |
