So what's your definition of economically viable?
There's lots of sites on oceans that are making water for fractions of a cent per gallon. For instance https://en.wikipedia.org/wiki/Minjur_Seawater_Desalination_P...

We just literally don't have the technology yet. It takes an immense amount of electricity/energy to desalinate ocean water which is way more saline than brackish water. The other half of the cost is in the very high rate of corrosion of equipment.
I'm not against desalination of oceanwater. I absolutely support funding more research into it. I'm just explaining the current state of technology. It just doesn't currently exist.
You seem to have advanced knowledge that is contrary to ~everyone else. It would be helpful if you would simply state 2 numbers. First, what you think it costs, and second, what you think an economically viable cost would be.
