Subjective value (at least in the Austrian sense) does not mean you just make it up and it can be whatever you want
Subjective value means you value a good based on the highest use to which you (the subject) can put that good
For Bitcoin that highest (and only) use is trading it to someone else, which historically does depend on fiat. When the value of fiat goes to zero (because it is no longer desired in trade), the value of Bitcoin will go to zero in the same way and for the same reason.
Why are you linking fiat to Bitcoin for no reason? Fiat is going to zero against Bitcoin. As the value of fiat declines, the value of Bitcoin goes up. It is not fiat, it is a commodity. If fiat goes to zero, gold doesn't go to zero. WTF are you talking about? Bitcoin is a commodity just like anything else. The only use it has is money. It competes with other money, they lose it wins.
It's not a commodity, it's a currency.
The whole "Bitcoin is a commodity" thing is a psyop, as is calling it a coin, calling the accountants miners, images of gold coins, etc
Define commodity - I suspect it will either be a uniform material or some incredibly complex definition that includes all the uniform materials + Bitcoin but excludes the other cryptos
Money is a commodity....
