If we think of a world in which a remote control does not get lost as
normal, when it disappears we get angry.
The above sentence has a "think of X as Y" construction. If you place "as Y" that far from "think of X", it might cause a confusion.
I advise you to rephrase it to:
If we think of a world as normal in which a remote control does
not get lost, when it disappears we get angry.
You could consider using "ordinary" in place of "normal" as suggested in the comment as it means:
With no special or distinctive features; normal: ‘he sets out to
depict ordinary people’ ‘it was just an ordinary evening’
