Also I like your potential energy analogy, but it doesn’t apply here. Potential energy is *actually* energy. It’s the measure of a force being exerted that *could* be realized. In other words, without gravity there is no potential energy. So we are just measuring gravity, which is present and constant. There is no force being “exerted on money” that would allow it to suddenly turn into energy in the same way. Very different mechanisms.

My test in the other post is the best way to make this obvious.
