This is naive. There's no natural process that ensures the network stays well distributed. If Bitcoin takes off, then why would the next hardware miner maker sell the product? Maybe they find it better to just run a significant portion of the market rather than deal with clients. 10 years from now, what if we have a handful of bitcoin mining firms, similar to the current role played by market makers like Getco or Knight? You can't just dismiss this point. You need to come up with some process that makes it more valuable for someone to be a small player in the network than to go all-in.
