Most "normal" currencies try to go to less cash, more digital currency. This is problematic because it make all transactions trackable and possible to analyze. Bitcoin is very very good for not having this issue at all, and still being digital (doesn't require any physical note or coin to be used).
With the upcoming years, new systems for paying easily digitally where you earlier used coins and note will appear (see tests with NFC and similar technologies, in mobile phones and similar) for the traditional currencies. The same route could be used for bitcoin, printing bitcoins won't be necessary. I think Hand-to-hand / AFK transactions can be simplified better in other ways.
And if I understand you correctly tieing the value of a bitdollar to another currency? This is not wanted, especially not if it is the US lollar because that one is going down way too quickly.
