(You’re a good example, because you think force gave fiat it’s value and a voluntarily adopted currency like Bitcoin is worthless)
You don't have to agree with me. If you hold the subjective theory of value as being legitimate, then you are wrong for claiming that fiat has no value since you are going against the fact that most people (including you if you're still working and paying taxes) are treating fiat as if it has value. Your own use of fiat as if it has value refutes your claim that it has no value.
Next time try reading what i wrote, because the subjective theory of value means exactly what you just described and i explained it like this. Maybe if you wouldnt ignore 90% of what people are saying your debate would even advance.
It is about behaviour, not just thinking it has no value. People are giving up what they value less for something they value more. People here are switching Fiat to Bitcoin, because they value it more. When i just needed fiat then i might exchange my Bitcoin for fiat, its an exchange where both sides benefit. That most people here hold way more Bitcoin than fiat, shows that they value Bitcoin more. It is not about absolutes. It is always subjective about what is being wanted or needed by the individual. Each good serves us a purpose with differing importance, there are many subjective and objective factors that can influence it and this can vary based on current needs and wants.
I can already deem fiat valueless in my mind, it can be almost valueless to me, i can prefer other things over it. No one here would refuse 500.000$ right now just because its fiat, because in reality they can still use it. And the same way you wouldnt refute 500.000$ in Bitcoin even tho its valueless to you. When people here say it has 0 value, they mean its purchasing power tending to go to 0 and that its not a sustainable form of money. And oftentimes people come here saying Bitcoin doesnt have value, and then coming up with the biggest bs to explain why fiat has value, but if we applied their logic to every kind of money, then nothing would have value. If you are so objective how didnt you notice it yet?
The subjective theory of value doesnt exclude: supply and demand, cost theory, objectivity, rationality. It just claims that value is something intrinsically human full of errors, uncertainty, learning, making choices, evaluating things individually. If value wasnt subjective it would just be a constant, but in reality were seeing how volatile everything is.
Humans has the capacity to be rational. It's a choice in terms of whether they want to be or not.
However, if you take the metaphysical position that human can't be rational, then I can see why you reject the epistemological concept of objectivity and its ethical derivative of objective values.
Can you read? I also never claimed humans are incapable of rationality, but oftentimes they try to rationalize their own subjectivity.
Subjectivity doesn’t exclude objectivity
