The salt can be put aside and processed for other uses.
It often contains useful materials in small quantities.
Ocean water contains uranium, thorium, etc etc.
Process enough salt out of seawater, melt the salt, skim off the heavier material, reprocess that for useful stuff, turn the salt into table salt.
Supposedly sea salt is the current “healthy salt du jour” with certain crowds.
Market the recovered salt to them, at a markup of course.
Last winter my company sold over 600 trucks of rock salt throughout the north eastern US. They mine it out of the ground in NY, PQ, OH, NM, UT. It is used also for water treatment both municipally and residentially for water softening(solar salt) and killing bacteria. So, there is money in salt.
