Global money supply doubles, not your personal money supply.
Global output/consumption doubles, but so does personal output/consumption supply.
If your personal money supply stays the same but personal consumption doubles, that is literally the value of your money halving.
It's not about a "sense" of this or that. It's the actual loss of personal value. The state is siphoning your value so they can stay at equilibrium.
