A new economy based on generosity, not hoarding.
Lets do an experiment, you give me all your bitcoins and I will give them to someone else, if he says he will also give them away and so on. Then lets look at block explorer and see how far it all went.
My best guess is that we will set off a chain reaction where every one just gives everything to everyone else who needs it.
I have thought of this a few times, but it wouldn't take long before someone hoards them and doesn't pass them on. We have six thousand years of conditioning telling us to hoard, and that won't stop overnight outside of a real social context.
