currently, people of all ages can easily access commercial pornography which then profits from the activity (either through advertising revenue or overt sales).

So in effect, due to not requiring and not enforcing age restrictions, pornographers are profiting from distributing pornography to minors, which is a crime and should be a crime.

Even if this fails to block access by minors, it will certainly to a much larger extent block the ability of pornographers to profit from illegally distributing adult content to them, and with that, the potential incentive to market to them and the attendant cultural knock-on effects this situation creates.
