In the future, almost every action user might do on an information system ought to be rolled back cleanly and easily once presented with higher priority key. That will make e.g. account takeover not worth the hassle.
But right now all the systems we use are frighteningly brittle.

This means rogue clique might roll back a few transactions, but they can't steal money from static accounts or create coins out of thin air.

No way to undo that. So there's still a reason for account takeover there, if someone else could consume on my dime by hacking my account temporarily.
