Except it isn't really an argument, so much as a question. In your example, the good created by eliminating polio are blatantly obvious to anyone who knows what polio is. For your analogy to hold, then the answer to the question posed must be equally blatantly obvious. This doesn't seem at all obvious to me, so fails as a rebuttal.

It's absolutely an argument that filters are unnecessary. It's not a good one. It combines survivor bias with the false implication that today's internet is the same one we had in the 90s; it is not.

I'm opposed to KOSA - I think vague appeals to "preventing harm" are going to be weaponized against queer kids in red states and cause real harm... but again, I think there are far better arguments against it than the "we came out fine" one anti-vaxers and corporal punishment advocates trot out.
