If you are going to build a system that needs a lot of water and the resulting product will be transported hundreds of miles to be used, why not start out where there is lots of water (an ocean) and a place where there are lots of pipelines (a port). hey, lets build one near an ocean port and skip the part about sucking water from the air. Naaaaa...cant get any money to study THAT. Wait!! Doesn’t it take a lot of energy to crack water into hydrogen and oxygen? Solve that and watch, oxygen will magically become a greenhouse gas and be BAD.
