Let's say Youtube's theoretical solution labels you as a child, even though you're not. Without some kind of way to get around that block, you've now lost access to Youtube.
Note that this scenario isn't entirely theoretical. It's rare, but there are already subsets of Youtube (trailers for horror movies are where I see this most often) that are locked behind a login screen because the uploader has indicated they're intended for mature audiences. You either log into Youtube (sacrificing some privacy) or you just don't get access to those videos.
This ends up being not a huge problem today, because the amount of content falling into that category is very narrow. Imagine a world where you fail Youtube's theoretical privacy-preserving test, and suddenly you can't watch anything, regardless of the content, that isn't designated as being specifically directed at children.
Of course, on some level that's just Youtube's choice. But now imagine if a government agency like the FTC dictates that every large Youtube-scale platform has to implement this test. Suddenly you find yourself not only unable to watch videos on Youtube, but also unable to make a Facebook/Twitter account. Imagine if you can't search for certain things on Google.
Note that this final scenario also isn't entirely theoretical with the FTC. My reading of the comments that the FTC commissioner has made is that the value of targeting Youtube is specifically that it's a centralized choke-point for this kind of content. I don't see any reason to assume that if creators migrate off of Youtube, that the FTC won't follow them and impose similar rules wherever they end up.
(I have a lot to say about content, including suggesting specific solutions to specific problems, but I’ve decided to not air this in a public forum. Further discussion is pay gated. Sponsor me on github for more !!! :))
