Good luck-- I share your view that coming up with better ways of playing zero-sum games is not the way to make the world a better place.
The fact that this statement is coming from the 'lead developer' of Bitcoin does NOT make me feel good about the future of the Bitcoin project.
Relax. There are others with strong economic basis that either are part of the team, or follow it closely. Theymos and Stefan Thomas are two names that I remember by heart, and probably there are others.
No developer in the team would be able to change the economic basis of bitcoin "at will", without provoking lots of noise at least.
