I’ve since I was a little child wondered about what money really is and I didn’t get any answers that really went to the bottom; for example, ”yes, gold is good money, but WHAT backs gold, WHY is it good money?”. And a couple of years ago I got some spare time and I discovered that people actually have taken these questions seriously and thought about them all the way down to the bare axioms. Money as a protocol, not a thing (even though things can function as parts of the protocol, leaving the protocol partially functional). After realising this bitcoin becomes the ultimate given (as money), at least for me.
