Note that you're just hiding complexity away into the word “interfere”

Just? If you think that my statement doesn't do anything more than hide complexity then you are mistaken in a sense very similar to this. I was referring to a human concept that a reasonable human could be expected to at least approximately understand. That's why we have words.

-- try explaining to an alien or an AI what exactly counts as “interference” and what doesn't.

Many things are hard to explain in full reduced detail. Sometimes it appropriate to attempt such an explanation. Sometimes it is better to just say "It's a tiger".
