Central bank? Inflation via derivatives? No, Bitcoin can't be centralized and dissolves the government power necessary to enforce the perverse incentives that created the present fiat money derivative situation.
Bitcoin can't be centralized? Now I'm not sure what you mean by being centralized. Look, I already encountered two contradictory ideas about what Bitcoin decentralization actually is, so what is your take on this? If someone grabs more coins than anyone else, would this go for centralization? Or, rather, what could in this case prevent their owner from inflating Bitcoin derivatives if he decides to?
