For the same reason we don’t utilize fission in other areas, people are ignorant and terrified of it, politicians are trying to be re-elected, and as a result real problems such as distributed rather than centralized storage of waste emerge. There are also real issues with processing vast quantities of seawater in a way that doesn’t destroy littoral ecosystems.
