the concept that bitcoin is borderless seems to be beyond most in this threads comprehension
When you have comprehended my posts in this thread, then you will realize that being borderless is irrelevant to the point of this thread.
You comment indicates you do not even understand. Perhaps you are too lazy to read and study carefully. Perhaps due to some ideological bias that blinds you.
Fiat has an unverifiable money supply, no party can ever verify the amount in circulation or how much was created at any moment in the past.
Broken, centralized, permissioned public shitcoin is different. We can see how much is there at any point! We can see if the ledger suddenly has new coin. Sure, I share your enthusiasm to prevent bitcoin from turning into broken, centralized, permissioned shitcoin but hey - that ain't fiat!
Indeterminate money supply is not the attribute that allows us to use the term fiat. Fiat means someone else is in control.
