Reason No. 2: The statement "1 BTC = 1 BTC" emphasizes Bitcoin as a standalone entity, completely untethered from traditional financial systems.
I'd argue that's not realistic. I don't hold Bitcoin "just to hold Bitcoin", it's a means to an end. In the end, what matters is purchasing power, and avoiding infinite inflation.
While numerically correct, "1 USD = 1 USD" fails to hold true in terms of value.
So does "1 BTC = 1 BTC", it just "fails" in the other direction (on average, measured in purchasing power).
