Immutability is worthless if theres a gaping hole in the underlying or overlying infrastructure built on the chain that allows people to basically cheat and steal funds out of others, that's why ETC have no argument, no logic and only a fringe opinion/baseless assertion that Code Is Law because there's no relevant explanation why and how immutability is above all else and that's why it's only assertion. That's why there's a maxim of law that says For every Rule or Law, there is an exception, because rules and laws aren't devoid of logic, ethics, or sensibility. It doesn't make sense to say that "Reality allows it" when it's a matter of ethics or morality and in the same way it's utter nonsense to affirm that Immutability is above all else, especially when the question is "when should the blockchain be edited, reverted or modified" to which the only acceptable and sensible answer should be Whenever a consensus forms (observe how, not why).

Sorry about the double comments and wanted to add that the only exception I see to Whenever consensus forms is exactly what ETC is: when a fringe few would rather die in obscurity instead of considering it an ethical problem as opposed to what's allowed by reality so to speak (observe why, not how).
