I don't understand what "power" has to do with any of this. What am I missing?
Let's play devil's advocate shall we?
Bitcoin currently has a market cap of around 125 million dollars (exchange rate 12.50 x about 10M coins). It currently returns over 19 million results on Google, is owned/used by hundreds of thousands of users, including several businesses, and has global reach.
Now, all of this has been based upon a
perception of what Bitcoin is. Key to that perception is that it's decentralized. If, from the start, the currency/system began and at its heart was a "Bitcoin Foundation" claiming to speak for it I doubt it would have gotten this far. This is because people's primary objection would be, but wait, it's
not decentralized!
People would be, justifiably, skeptical. Who are the people that run the corporation? How many of the coins did they get? How much power and influence over what exists of Bitcoin do they have? Etc. The people would have speculated that surely if and when the project grew this representative entity would amass more wealth, power, and influence. How could it not? A lot of people that got involved would have said, no thank you, I'm quite sure.
Now, let's look what really happened. Bitcoin did NOT start this way. It was marketed as decentralized, and because there was no perceived concentration of power, it essentially was and is. This allowed the progress to date. But, now enters the representative entity tending toward centralization of power. Regardless of how it says it's designed to be benevolent in reality there are many ways it can and will acquire power. One example: most people don't know of Bitcoin. Let's say enough people start thinking TBF is truly the deal representing bitcoin. They will begin referring to it as such, including word of mouth and giving such link juice to Google. This would only increase over time. Can you not see how this entity begins to have a monopoly of anything regarding Bitcoin? But back to the example, new people start to learn of TBF first because that's how the world perceives Bitcoin is represented. Many go straight to their site, rather than anywhere else (where dissenting voices may be) and they donate and/or read into and become involved with TBF's version of Bitcoin. There are always at least two sides to any story, but new users would always only get the one side. That's just one example of where the power comes from. Another quick one is (clandestine) meetings of high level members with powerful outside entities, like VISA or U.S. gov, or TPTB, take your pick.
EDIT: one way I see to alleviate the pressures and problems I point out above is to have the entity intentionally seek to deflect and LIMIT itself amassing power. I'll therefore ask my question yet again, for the fourth time below...
