[Star Wars] Why doesn't Tatooine import water?

Uhh rather simple question. Water is so scarce they extract it from the atmosphere using high tech devices. I feel like with the prevalence of faster than light travel and privately owned ships someone would find out there was a killing to be made selling water. Is there some kind of conspiracy with the Hutts who use water to control people or something?

Atmospheric extraction is cheaper. With a mass of 1000 Kilograms per cubic meter shipping water from offworld would be prohibittively expensive.For reference sake. One cubic kilometer would weigh a BILLION metric tons. Real world Earth uses 4,600 cubic kilometers a year.

2nd, Tatooine isn't really an economy whose GDP could afford importing so much.
