Parts of what you just said are not really a proper response to what I said, either because of accuracy or relevance. So I'm just going to address the one important part of what you said, metadata. I didn't consider metadata because I treat proof of age as what it is, proof of age with proof of identity being incidental. If visiting a website requires handing over my full birthday, "hardware ID", or real identity then I would be concerned, but we're not there yet. It's a widely held view in the general public that you should be able to browse the internet privately just like you should be able to browse a library without the government seeing a log of every book you read, and I hope that would be enough to resolve this. The general public is not very concerned about browser fingerprinting, which effectively erases user privacy, but government mandated sharing of your identity online would be a red line that would get the normies involved.
