Lead paint has very obvious, bodily harm to children. Do ads harm children? Perhaps, but even if they did, there's no cost to visit a free-site without ads, or pay for a site without ads.

What I did was make a hypothetical that was more extreme, with an analogy of the underlying reasoning, to make my objections to that reasoning more apparent.
