Money is leverage you can use to get someone to do something for you **cleanly & fairly**, now or later. It "stores" nothing, and since the future is always randomly uncertain, we really can't quantify its value beyond this moment, but we use approximations (estimates, projections) to get as close as possible.
Storing energy literally is one thing, but holding bitcoin isn't that.
Even the hardest, scarcest money is still virtual by its very nature. Producing it, or anything else, is what's real.
