right, that's exactly what i was getting at with my original comment. none of the laws we have are 100% effective. so i find it weird that this specific topic always devolves into "well some kid will be able to get access, so your proposal sucks".

> little twelve year old Jimmy obtaining access to porn evokes some kind of far more visceral reaction in Jimmy's parents

Because right now there's next to no barrier to access compared to Jimmy getting himself a beer. If you keep saying "Your proposal sucks because it isn't perfect and we should do nothing" then you're essentially surrendering to the people who really want facial scans.
