Bitcoin's actual utility compared to Gold or the dollar is worlds apart, we know this already. And so, the only actual advantage that gold/dollar have is that of it's perception by the majority. We know that Bitcoin is a better a store of value, and better to transmit value with.
1. The actual utility of bitcoin may in some cases be a bit better than that of gold, but it is certainly not when compared to the dollar. Or any other fiat currency. Bitcoin is far from that level of utility. If you don't see that, you need to have a better look.
You're confusing utility with acceptance.
