Salt can indeed be removed from water, by a process called reverse osmosis. There are a certain kind of membranes that can filter off the sodium and chloride ions. But, reverse osmosis is not a low cost solution, that's why it is not very economical.

Boy I must sound dumb.
The question I was asking (among others) is why is it SO hard to get drinking water?
Reverse osmosis is just too expensive an option for most of the planet
I don't understand
why "there really is no chemistry of salt".
