As I understand it, it arises as a result from low fees. A very low incentive to forge.
But system needs thousands of independent forgers across the world, while merchant community's rising up. But after that how do u insist forgers to install code that makes their buisness a waste of time?
IMO: better way is position forging as business. Someone'll bake bread, someone'll forge to secure Nxt ecosystem. I don't see so much difference. IT-business for everyone. And good way to redistribute money.
