If you want to fly from New York to L.A., you get online and get an almost instant comparison of most of the different major airlines, their prices, the days they fly, layovers, etc.

If you want to purchase products, you do the same... at least for many different kinds of products.

Barter is only one further step. Bitcoin is a medium of exchange that takes most of the power away from the controllers of the world. Computerized barter would take it all away. Bitcoin is the stepping stone to computerized barter. Computerized barter compares and trades not only products and services, but wages, as well.

Once MaidSafe (or something like it) gets going, Internet will be ripped out of the hands of the controllers. Once a full barter program gets going, where one barters perceived value of everything in life that he barters, the true value of jobs will present itself. People will be paid based on what they can trade their self-worth for. They will be paid by products and services rather than by Bitcoin. Fiat will be long gone.

Once this catches on, there will be no stopping it. Innovation will be based on true innovative value, rather than some private interest group or company manipulating the world by keeping an invention off the market.

Free energy will come about, because Tesla inventions (and others) won't be able to be stifled any longer. Then the stars will be open to us.
