This particular thing seems unlikely though, trading actual energy would be pretty impractical so even in the worst ancap dystopia corporations would probably at least come up with some kind of currency that represented energy. Unless things are so bad that there's not enough stability for currency to be worth anything, in that case people could trade actual energy but that would really just be barter since there's no real reason they wouldn't trade other valuable shit too.

So I feel like a sci fi world where people pay for stuff in unexploded bombs is kinda just bad worldbuilding.
