I'm not certain that I follow what you are trying to say. Oh sure, dueterium is slightly more plentiful than uranium, but uranium is found in abundance in the SouthWestern U.S. as well as in Alaska...and in these days of breeder reactors, I'm not even sure that raw uranium reserves are a big deal, either.
I think that you'll find that processing dueterium from sea water is comparable to mining uranium in costs, too.
So I don't see a large advantage to fusion over fission. Both use fuels that are in abundant supply, and both methods provides comparable amounts of energy at comparable levels of safety.
Fusion simply leaves behind less waste. What's the big motivation there?!

Don't forget that Uranium is also found in sea water and in a large enough quantities to "mine." Using nuclear desalination plants, especially in the west where water is needed, nuclear plants could be used to provide electrical power, water, and fuel.
