Honestly, I don't think it matters at all.

If the price of a Bitcoin is $0.10 of USD... then you do need a lot more Bitcoins... but Bitcoin would also be easier to get because the difficulty would be adjusted. It doesn't matter what it the value is compared to USD or any other currency, because prices would adjust accordingly.

If Bitcoin was $1USD, and stayed at $1 USD forever, I think that would be great, because then we could concentrate on the actual value of the currency; the speed, the decentralization, the feelessness.... and work on getting it accepted everywhere and building applications that can use this global currency.

Obviously, that's not the case, especially since 21M coins will ever be printed... but this constant obsession with price is confusing to everyone who might adopt it and makes it less useable for those who actually want to use it... and that's a huge shame in my eyes.
