OK, so let's not speculate and go back to my initial point, which is simply theoretical:

Aren't the currency function and the store of value function inherently at odds, due to a difference in something as fundamental as the need/convenience of a capped/uncapped supply?

I argue they are, and that BTC by design is good at the latter. So insisting that it must do the former as well is foolish.

That's what I'd like to see arguments against.
