You misunderstood, I said that theory of value is relevant for this discussion and not offtopic, of course when creating money and value its useful to know what money and value are.
I'm not sure we're on the same page. I was specifically arguing against the idea that the amount of energy used to provide a product decides some portion of the market value of that product.
It was put forward that because it takes more energy to produce Bitcoin it must have a value that exceeds PoS. Put another way; because PoS doesn't necessarily cost very much to move and produce, it is a less valuable currency.
Peter Schiff implied the same sort of fallacy when he was insisting that Gold was a good purchase when it fell to $1200/oz because he argued that if it fell any lower than that it would cost more to mine than it was worth. It then fell down to roundabout $1000/oz. The point is that $1200 was clearly not some kind of floor on the price, just because that's presumably the cost of production.
Yes, surely this is a very practical question of the actual organization of production, if there are some people that can mine for less, they will use the opportunity when the value drops, but what seems to me almost as important is their share of production, if they have a monopoly it seems that the optimal for them is to keep the profit rates at the level that exclude competition and still give them maximum possible profit, because thats a better situation for them than just temporarily increase profits. The absolute equilibrium of value is just 0, everything else is uncertain, variable and depends on context but that doesn't mean there are no rules in this chaos.
It's putting the cart before the horse. Gold isn't valuable because it costs alot to produce; It costs alot to produce because it's valuable.
Similarly, bitcoin's aren't valuable because they cost a lot to produce, they cost a lot to produce because they're valuable.
For bitcoins this is true, because it is designed for this to be true (difficulty), however this doesn't mean that its true in general, or that this is the dominant factor, we could for example think of it as a feedback loop of value, that increases the difficulty and difficulty that increases the value.
It depends on what you meant by "adequate". I took it to mean we don't have a way of even theoretically deterministically arriving at prices. That would be true because value is subjective and non-deterministic.
That doesn't mean we don't have theories that at least show us why it's subjective and non-deterministic.
No, prices could only be determined if we determined prices to be so, prices can be both deterministic and non-deterministic (otherwise either competition or price fixing would be impossible in practice). But its important to distinguish between price (as quantified exchange-value), exchange-value, use-value and value in general, and this is what I mean that we have no adequate theories of value, no valid scientific model of value in general and exchange-value in particular that would show why and how it is subjective/objective and non/deterministic in a way that physics has a adequate model of atom, and because it has it knows that it can't measure spin&location at the same time.
I can see that the fact that they're valuable, which drove up the cost to produce them, also made it more secure, which may make it more valued by consumers, and so on, but it's important to see the direction of causation here. I know it wouldn't be right to say energy used to produce bitcoin doesn't have anything to do with it's value, that's why I said it's tangential.
I do not see the cost of production as a way to argue in favor of PoW, or to show some failing in PoS. In fact, the whole thing is pretty ironic considering PoS' primary selling point is that it uses less energy to provide it.
It's not the direction of causality that is the problem, is not a either/or both can determine value more or less in more and less determinate and immediate ways. It seems ironic, because there are many functions done by the same mechanisms in crypto, Bitcoin is a very elegant construct, but elegance is inefficient, its always better to separate functions and optimize them one by one than to bundle them together, except for actual use where they have to be bundeled for ease of use.
Thanks for comments
I think this discussion is appropriate and have always been intrigued by the linguistic coincidence of value from proof of work and theory of value from work.
Fiat could be considered in the same way, its costs are not immediate labor, but mediated labor, because to issue new money the costs a goverment pays is credit.
I'm not sure I understand this point. If I print a million new Harriet Tubman 20s, where is the mediated labor or credit cost? If I create a bank account with a trillion USD in it, as Lord Blackwell was recently complaining about, where is the mediated labor or credit cost?
You don't create the million in a vacuum, if you do you have a new, probably worthless currency. If you create a million in a monetary system that has rules for its creation the rules have some cost associated with it (buy goverment bonds, lend money/assume risk etc.) and the other type of credit is enforced on the population as the decrease of real wages and general buying power and living standard. I've heard about how Bitcoin is supposed to be apolitical, and it is to a degree, but only because it has its monetary policies fixed, what would have to be determined is if they are in fact good monetary policies, and thats for alts to explore.
This is great, I've always had a problem with Gresham's law, because it was stated in its simple, false form.
