Anyway, the forces of physics can be resisted: A thrown ball goes against the flow of gravity, and even Airplanes and Birds can fly for extended periods of time. But in the long term... almost everything follows gravity in the long term.
Similarly, centralizing market forces (in particular: the formation of "natural monopolies") are a known and documented phenomenon. But in the long term, the BTC Market gains more benefits from centralizing... than decentralizing.
