"absolute scarcity automatically equals value" is a fallacy Value is subjective. Value is a function of supply AND demand. You can't control demand. Any good btc maxi that is obsessed with austrian econ should know this 101 fact but surprisingly few do. That should be plenty to at least ponder that you might be wrong. https://github.com/libbitcoin/libbitcoin-system/wiki/Scarcity-Fallacy
I admit the possibility, even not so improbable, that even if bitcoin is a scarce resource could fails to detain value for some reason. I admit also the possibility that some shitcoin could detain value for long time like or better than bitcoin, but I consider it less possible than a scenario where dog-like aliens come to the planet earth in flying toyotas ufos singing taylor swift songs.
