It's a fallacy to think that bitcoin will centralized to the point it will be controllable by a single entity just because it scales. I mean, how can it be more centralized than having 8 mining pools providing 75% of the total hashrate?
Do you think internet is decentralized? Because it is and does anybody have the capacity to run an ISP? No. Only big companies does but noone controls the internet.
My point is, if it truly becomes the system of our dreams, where everyone uses it for everything,
wouldn't the government co-op it under National Security interests and mandate total control in ways unknowable now?
I'm not concerned about non-governmental centralization, only the centralization that can effect an individuals rights.
The internet is not controlled by anyone, but it can be shut off in many countries during emergencies or "other", including the USA.
Which government will control bitcoin? US? China? Russia? France?
Well it all comes down to, who wants the most economic control?
If you can control this system (when it or if it becomes full mainstream), you can control the world, ultimately.
A new era of economic control over humanity can come into existence, if governments take actual control to the system.
I assume the USA would attempt control, China Gov doesn't really trust or understand it, or pretend they don't.
There may be mandated Government Transfer Nodes that all nodes must pass tx through, in the USA, I don't know.
If your Node or company Node does not pass the data, that Node is considered illegal and will be raided under new laws.
I see it like this... Coinbase, Bitpay, all those companies must conform to regulations and laws within their respective countries.
They are based on bitcoin and sell/trade/etc bitcoin, but they must conform to the laws.
But Bitcoin/bitcoin is outside all of that, currently. It can not conform nor be controlled in its current state.
We can not allow Bitcoin/bitcoin to be regulated or changed to allow it to be conformed into a normal company and be governed by laws.
And I ask again, Is it really possible to have our cake and eat it too? I don't know, I have no technical background.
