Let's be honest, governments won't like the idea of legalizing things like Bitcoin without being in charge.
Not really
There's difference between legalizing and making legal tender
Bitcoin is legal in quite alot of country so nothing new.
And laws are meant for the good of societies. Besides, that's what being governments is about — to govern or rule according to laws
And here I thought leadership was to serve.
as everyone may need permission to run stuff like node, and the one who gives the permissions, controls those the permissions are given to, which consequently means centralization of control and power.
Running Nodes don't work like that
The best they can do is make running nodes illegal and there are ways around it
Not to mention the world government are not united.
self-regulating to the extent that governments will see no reason to control Bitcoin,
This is wishful thinking
First who's regulating? When there's no head
And find a reason? Who wants something will always find a reason
No matter how lawful you act.
we need a decentralized and privacy-preserving alternative to kyc which will be used for exposing and preventing scammers, thieves, sybil issues, etc
Lol like a decentralised KYC?
KYC, Privacy or decentralization don't mix
They contradict.
We need fast and "feeless" auxiliary Bitcoin systems, like sidechains, to complement the main chain.
I think I would stop reading further here
Because I'm shocked someone would even think about No fee with Bitcoin
When it plays a role in its security.
