This means there are no valid concerns.

There are just things some people want and the reasons they want them.

So the question that you are so annoyed by remains unanswered (by you anyway), and so, valid, to all of us adults.

@hypfer gives a valid concern, but it's based on a different facet of lockdown. The concern is not that the rest of us should be able to break into your phone for our safety, it's the opposite, that you are not the final authority of your own property, and must simply trust Apple and the entire rest of society via our ability to compel Apple, not to break into your phone or it's backup.
