The way I see it, this isn't really about capacitors. You could do the same thing, not practically but conceptually, with a rechargeable battery.

In many ways, a capacitor is just a shitty battery

I think conceptually any circuit element with reactance/memory would do, just a matter of cost and spec

I don't think it's useful to think of capacitors as bad batteries. The only point I was trying to make is that a component doesn't have an inherent "ground", so you can reference one pin to any voltage in the circuit.
