BUT would you forget about all of that and go for a alternative technology with better features, once it is developed by all these banks? {Permissioned, private ledgers} They will obviously just copy the concept and
I don't even understand how this is a question. Wasn't the initial goal to take away the power of the banks? Why are you even here?
I think you're misunderstanding what a full decentralization is.
Correct. Bitcoin's strength lies in its decentralization.
If objectively superior features are developed elsewhere, they may be integrated into Bitcoin. In fact, many already have been.
Exactly, as long as these features are open-source as well.
Well, they will not develop something trustless, but they can make it decentralized.
That's not decentralized.
