But as usual google wont inforce it. So those well behaved webmasters will earn less than the cheaters.

Not necessarily. Google is a company that was built around automation, and in terms of scalability, automated incentives and disincentives (such as smart pricing, "quality scores," etc.) make a lot more sense than playing whack-a-mole with every individual nitwit or scumbag who tries to game the system. Starvation kills just as surely as shooting does--it just takes a little longer and isn't as dramatic.
