You miss the point it does nothing to fix the current monetary system.  The fact bitcoin is designed around having built-in, rent seeking middlemen who you need to ask permission from to move the coins you supposedly own, and then need to pay a ransom extortion fee to, should be a red flag to any non-idiot that bitcoin at it's core does really nothing to alter the evil banking system that currently exists.  The variable of fixed money supply in bitcoin vs infinite fiat supply is pretty much a giant red herring to distract people in this regard.

The real issue at hand isn't the variable of supply, but the ability of people to insert themselves into the middleman position and siphon off wealth while doing virtually nothing, collecting infinite interest, and ownining the entire planet in the process.  The banks do this in their current business model, and both bitcoin and the lightning network are designed the same way.  So nothing really changes in the end.

Physical metals, on the other hand, DO NOT have built-in middlemen like bitcoin and the current banking system do.  If I attempt to spend a bitcoin, I am involuntarily making someone else rich in the process - the designed to centralize, built-in middlemen mining monopoly or lightning node monopoly.  If I attempt to spend a gold, silver, or copper coin, NOBODY else is profiting off my transaction and sucking up all wealth in the universe in the process.
