Bitcoin is not against banking. It is against a central issuing authority over the monetary system. Banking on the original protocol will benefit everyone. Banking on Liquid/Lightning is just federal reserve 2.0
That's the whole point of a p2p currency to have full control for yourself. And loans can be achieved in other ways like crowdfunding. Cryptocurrencies will fuck up banks!
Then why would they want crypto currencies in the first place? They will just have no benefit of them. They will go down with the banks or banks will win and crypto currencies go down.
The benefit is that they have the possibility of holding it themselves. It's easier to have it all in one (open) system than to switch between open and proprietary systems.
And so taxes can be automatically withdrawn from your Liquid BTC account...errrr node....uhhhh whatever the f*ck they are calling their Federal Crypto Bank accounts.
