your assumptions are based on bitcoin price not rising to keep pace
it has succeeded in doing that for 15 years because it was well designed.
arguments against the mechanism by which it achieves that are based on keynesian economic models which have been used by central bankers to promote the idea of a constantly inflating monetary system
bitcoin's ongoing operation disprove this idiotic thesis, and trying to use this to fud bitcoin as a fanatic for privacy coin simply fall flat. carry on with your fantasy as much as you like it's not going to change the empirical facts that bitcoin WAS designed well and no shitcoin has been able to get a word in edgewise since then.
it's a waste of time, but it's your time that is being lost. life is not eternal. principles are.
