Well, if you look at the US, similar laws are being enacted at the state level as those you see in the UK, often by the same people who would reject the other features of governance you see in the UK (the NHS, stricter firearms regulations, etc.) because of them being "overbearing".

They are overbearing, this UK-esque "do you have a loisence for that" governance, is exactly why we have a permitting crisis in SF.

Aye, but the one thing you very likely won't have in SF is the need to have your government ID stored in a system in order to view NSFW material.
