The power already is centralized to a strong degree. But with an actual statelike system we would have full legislative power through democraticly elected parliaments and governments. With that more changes could happen, as they would now be represented, instead of having the mutant-organizations of comission and council without triple and quadruple indirectness between them and the citizens. That is where the lobbying power is so successfull. Because there is no democratic representation and hence no accountability in these structures.
