Bitcoin is a protocol which can be built on top of.

Bitcoin is not the end-all be-all to its own functionality. 

Services can be created on top of the Bitcoin protocol which provide instant transactions necessary for different types of commerce.

We need to stop thinking of Bitcoin itself as the "whole package". 

It is a foundational layer like TCP/IP.  On top of that layer, you've got Ebay, Monster, Esurance, Napster (lol)...etc

On top of Bitcoin you've already got MasterCoin Foundation, Gyft, and even insurance services guaranteeing the security of your wallets.

Much more is coming.
