I used to believe that but having seen repeatedly what happens when small decentralised groups get to decide (cf. HOAs in the US, housing cooperatives in Sweden), it's clear that there are too many nutters in society that seek power for power's sake and adding 20 levels of decentralized decision-making only means we'll have NIMBYs everywhere for anything new.

Having seen government work from the inside, what we need is clearer processes and _more_ centralisation - computers today enable the processing of amazing amounts of data in an extremely short time. Why do we need fourteen regional authorities to handle forms filed in triplicate?
