That already has happened which is why people forked. You can live in denial of that fact if you wish but a minority "lost" the "vote" and forked Bitcoin.
The BTH/SegWit2X fiasco shows Bitcoin isn't "more" decentralized than an oligopoly, an oligarchy, or a plutocracy.
> Bitcoin was made with the idea that a 51% attack would be unlikely and unfeasible; as long as that holds, I'm not sure what value your comparison has. You might as well make a comparison to any other possible disaster. ("A solar flare is a form of state governance that will destroy the value of your coins...")
The fact pro-bitcoin people swear up and down that isn't the case doesn't change the fact that they are effectively the Bitcoin state and that 2-3 of them + a number of smaller people can effectively "vote" to pass "laws" that are enforced against your BTC regardless of your wishes.
Simply because they don't outright steal your BTC doesn't change the fact you have to comply to retain the value of your BTC.
