I understand the perspective on objective fungibility (and its definition) that you are correctly describing. But it’s also (and only) true based on the system in which our experience and interaction occurs. That is to say because there is a massive set of agreed upon premises; that is the way fungibility works.

But just as with any concept, mental framework and most particularly societal heuristics, it is A) an entity of the mind (you can’t touch fungibility) and B) only remains true/valid until a consciousness revolution takes place.

I want you to know I’m sort of playing devils advocate here but Id ask you to broaden your threshold for possible simultaneous accurate perspectives. Its a basic tenant of Bitcoin that it holds a mirror up to the house of cards that fiat is. Its BTC 101 to understand that a 20 dollar bill is actually just a piece of paper. Its not the paper that is of valuable material; it’s the belief behind it. The collective acceptance that how ever many jumps down the layered money line, there’s a backing at the end transmitting assurance of value.

There are people in tribes that no doubt would see a dollar bill as just paper. And as current events and inflation show, the value and regard for those USD is changing, globally. But they are all still the same pieces of paper.

so, accepting what I just laid out as true and valid; you can’t talk ab money without including consideration for value. And value being also a mental construct is subject to change, conscious or un.

so yes it would be ideal that Bitcoin would receive a BIP that increased it fungibility; but I prefer to recognize another core aspect of Bitcoin. It is not an asset or entity under the umbrella of the current monetary system, or even societal perspective. It is a separate and closed system all of its own.

because of this I argue that there’s actually nothing a government can do that’s any different that a basic street mugger. They can make labels and lists and say any coins that exhibit x,y,z. are illigitimate: but that carries no weight in the Bitcoin network. They aren’t going into the code and altering it to reflect their preferences. Thier demands and regulations only exist in their fiat world and fiat brains.

You are not wrong. But I’m absolutely correct as well. Society is nothing if not a set of unwritten, agreed upon rules.
