> Websites should be allowed to decide who's visiting them

No, hold up, you just casually introduced a dystopian goal of facilitating the casual collection of government ID by website operators. I absolutely do not want the equivalent of South Korean ID numbers in order to do pretty much anything online.

Anyway as I always point out when these threads come up we've yet to try the simple and noninvasive solution. Websites should be required to send a content categorization header. Large enterprises that fail to do so should be fined. If that were uniformly happening it would then be possible to do proper client side filtering (right now that fails miserably).

Before anyone asks, app stores could be required to implement the equivalent of the header in an appropriate manner of their own design.
