Depends on whether the rate of salt extraction is precisely equal to the inflow over the long term. The Great Salt Lake is extremely salty and basically only two species can live in it: brine shrimp and brine flies. With about the corresponding level of "tourism" you'd expect.
And that is with industrial levels of salt harvesting. Would we expect the salt harvesting of these inland seas to be equal to or greater than the daily inflow of salt via the sea water? Seems dubious to me.
On the other hand, there are still many other benefits. Migratory birds love the Great Salt Lake. The Great Salt Lake Effect[0] on precipitation in this desert seems unambiguously positive.
