My point is that this privacy dilemna exists only for sites like pornhub, which offer it for free. I can go to a convenience store right now and by credit for a large porn site here. It's "private" in the sense that everyone in this discussion seems to believe it to be. The fact that it's paid means that we can have privacy-preserving purchasing methods because there is money that helps to finance these checks. Hell, pornhub could easily set up a "gift card" system where you have to go pay a dollar somewhere to get your age verified. This is far from an unsolvable problem.
