What am I falsely equating? I don't think that the store of value argument is absurd, even with real world assets like gold their value is really just socially constructed. I don't see why it couldn't in principle be the same for bitcoin, it just needs to be the biggest cryptocurrency and concrete the idea of it's own value in people's minds for a long enough time, until they take it for granted. Whether that actually will happen I don't think anyone can say. I think it's a mistake to assume that the value here has to do with the technology, e.g. the "best" cryptocurrency must win. It's likely just long-term momentum.
