I though Bitcoin was a way to avoid control and meddling. I'm not convinced it can work now which is a pity.
Or do I have the wrong take on the handling of this 'bank job'?
Wrong take.
Bitcoin transactions cannot be rolled back.
What you are talking about is ONE bitcoin exchange, and even then, they didn't 'adjust bitcoin prices'. They simply removed some of the trades that occurred during an intrusion into their database. After that, bitcoin prices were subject to market forces as usual.
