I think the "surveilance capitalism" and centralization of companies like Meta, Google etc has made many of us very sensitive to any systems that will leave traces of us against our will, be it porn, flock cameras or anything else that is similar.
I think we would have a lot less of a pushback against such policing efforts if governments had done a better job at reigning in tracking on the internet from the start. "Porn websites should check your age" is not that radical, but in a world where it doesn't feel unrealistic that much of the information about you is correlated and processed in ways that are not in your personal best interest, then it becomes another loop in the proverbial noose that can be used to hang us all.
