If the market want credits, they will get it. Beside, bitcoins is already decentralized. What more decentralization do you want?

He/she/they want an easier way for The Crowd to control The Policy-- right now, if you know enough C++ to modify and compile your own version of Bitcoin and can convince enough other people to use your version, then you can change Policy.What the hell are you asking?
Allowing everybody to tweak Policy and having some sort of mechanism that figures out what "everybody" wants to do is an interesting idea. I have no idea how you could actually make it work, and it would open up a whole other can of potential security problems (what if somebody controls a bunch of IP addresses and decides to "vote" for a policy that benefits them? or can you tie the policy changes to proof-of-work somehow? How do you aggregate what "everybody" thinks in a non-spoofable way? etc etc etc)...
