It’s a reason enough to be skeptical. How often have you read on here someone saying “can’t you just do x y and z” to a problem that is grossly more complex than the commenter initially appreciates?
A better stance would be to take such pitches as an interesting take but one which still requires peer review.
Edit: Remember when Musk tried to pitch a submarine to save those children stuck in a Thai cave and how local divers have to point out the passage ways were too narrow for even Musks child size sub? Being smart doesn’t mean you are equality qualified to resolve hard problems in other people’s fields.
It's an excuse not to think. Now, if you feel that YOU are not qualified to evaluate the idea, that's a different story. Don't act on the idea until it comes from someone you trust. But that's no reason to tell others it's unworthy of their evaluation.
