No, this is not right. A completely decentralized society is an utopian dream. Going to the roots we as humans are social creatures. We need to leave in society. You can't just condemn the ones who were born with lower intelligence or who are handicaped in any way. That is why we need to pay taxes  --> to maintain somehow of an equilibrium in the society + fund public property and services like police, firemen, doctors, etc.

Polarization of society classes creates conflicts, very ugly ones I might add. I think the best way is to find a balance between centralization and decentralization. The financial system is especially broken creating big problems so Bitcoin might be the solution for it, indeed.
