I think this won't actually work. I can see the idea but at a tx level
it is broken unless you take a view that everything is worth something
in my home currency at that exact moment in time and never changes again.
I think this is an absurd accounting view when fluid assets are available.
I think Alex has thought things through from *his* POV and agree in
general that a person should support their irrational thieving
government, if my government payed me to lie I'd propose something similar.
I am against what Alex proposes because it is so unclear what he intends.
Alex: let us know what you mean, then we can progress.
