They acknowledge the philosophy was inspired by the gold standard but their charts exclude gold. If you put gold in the charts and remove SLL it would provide a more constructive comparison (USD vs BTC vs GOLD)
I've never understood the notion of bitcoin as a commodity.
Money, in the abstract sense, is value that you have given to society, that you have not yet redeemed. It is a token of a half-completed trade. Bitcoin is an excellent implementation of that abstract idea.
I don't see how bitcoin fulfills this. Not that the early adopters and inventors of bitcoin don't "deserve" the many coins they have, but they have not received that as compensation for having given anything to society. The same goes for fiat: what value has the ECB/FED/govt given to society that justifies them being able to redeem the enormous sums they print up?
With fiat, money is debt. With bitcoin it's a commodity ("some finitely available thing", at least). Your abstract idea of bookkeeping who owes what or is owed by "society" is pretty,.. well: abstract and not very applicable anywhere I'm looking. Bitcoin is an excellent implementation of something different. It can't be an implementation of what you talk about, because bitcoin has no concept of "value being give to society".
I think you might be talking about karma. :-)
I disagree. If you have bitcoins, that shows that you did give value to society either by securing the Bitcoin network or by exchanging other goods and services for coins. I think your issue is whether you gave "enough" value to justify the potentially-huge appreciation in value you may reap if your coins become more valuable. I think so. We're taking a big risk on an untested but potentially world changing technology. If there were no chance of a big payoff, there'd be no way to bootstrap Bitcoin to the level it needs to be successful.
But no, the fiat printers didn't give value. And that's why the system is breaking down. They're only able to receive value because of a government granted monopoly backed by the threat of force. Bitcoin is voluntary and that's why the information it provides about value is more reliable.
ok, maybe bitcoin fulfills your abstract money concept of "accounting of value one gave to society". It may even do so in some kind of a fair way.
Let me argue however your original question why some (or in this case I) think bitcoin can be viewed as a commodity money:
The feature about "commodity" that is relevant for a money is its "rarity". Bitcoin has that feature and can therefore be called a commodity money when talking about types of money.
I can argue tangibility in a similar way: The feature of "tangibility" that is relevant for a money is the ability for someone to deny access to the "object" (no third party risk). Bitcoin has that feature and can therefore be called "tangible" when talking about money.
Does this help you understand why maybe some say bitcoin is a commodity money?
It's quite a stretch that goes against everyday use of the terms, but I think it is very useful to categorize Bitcoin as a tangible commodity money for marketing purposes... and it's not wrong, is it?
