In that case, most of the billions would probably accept a very marginal
increase in their chances to get cancer, or whatever other adverse effect
temporary Project Orion vehicles launches might generate...

Possibly. Let's say however that Project Orion vehicles were already
feasible, in principle, with the technology of the sixties, while I do not
