Your overall point stands, but I can see where the original poster seems to be coming from. There are "anti-radiation missiles", which lock into transmitters to blow them up.
IE: The AGM 88 "HARM" missile does this. But these are not used by air-superiority fighters like F22, but instead by "Wild Weasel" fighter jets against ground RADAR targets.

I think the poster you responded to magically assumed that a AGM-88 would work against a balloon. But that is mistaken: the balloon isn't transmitting enough of a RADAR signature for something like HARM to lock into it.
