I don't think laws should be enforced at any cost, but if we can reasonably enforce laws I think there is a duty to do so. Then there is also a different question of whether we agree with the laws on the books, but that is a different matter imo. Personally I don't think we should limit access to pornography as strictly as the laws says we should, and I don't think the ills of social media are solved with a simple age limit. But that is a separate discussion from the implementation of a (in my eyes) reasonable approach to age verification
