Decentralization = lack of leadership, lack of one vision and plan, lack of anyone responsible for failures. And it means slow decision making process.

I agree with this as many good ideas do not come to fruition because they haven't got people at the helm to drive through adoption. As soon as you start rewarding those who contribute you are back to power in a few hands. So in a political sense, decentralisation is difficult to achieve. It is a utopian idea.
