Oil and gas and other fossils are finite resources, and we need to replace them anyway sooner or later with pure electrical solutions, better sooner, as we know. And then what I said applies. And, as the only "infinite" resources we have, are the sunlight and the gravity of the moon, it is obvious that we should base global electricity generation on them.

That's with breeding, not with existing commercial reactor designs.
