You've added a restriction that it must be changeable by an individual. No such restriction should be expected when calling something immutable. Immutable as a term on it's own in binary, it is changeable or not. I also specifically stated that it relies on the definition of the blockchain being the currently accepted consensus. That does not include backups and rogue chains.

In the fully possible scenario I described it is clearly not immutable. Not everything is a paradox and our universe has binaries.
The probability of it happening has no bearing on whether it is immutable. The ability to change it is baked into it's design. Just like ethereum is not immutable they changed the blockchain.
