We've managed spent fuel for decades with very little incident. Meanwhile continuing to power 80% of the world with combustion of fossil and biofuel kills ~8 million people per year. Comparing the very hypothetical tail of spent fuel risk to current and very real 8 million deaths/year is extremely difficult to justify.

Oh yeah and combustion also causes climate change, which brings in all sorts of additional risks on top of the air pollution one.
