But again, oil is a natural resource, neutronium is not. Unlike oil, it would have to be created, not mined or drilled. At best (assuming we could create some) it could be used to store energy, like a battery, but not as a source of energy. And there is another problem: it is unstable unless held together by insane amounts of gravity. A small amount of it would just explode as soon as it was created.
I agree that there are technological hurdles to overcome, for sure.
It’s beyond on us on this side of eternity and only after the coming of Jesus might we develop as a society enough that this becomes a possibility.
Just as the saying goes in the nuclear industry, “It’s only fifty years away”.
