Using the neutral term "information" here is doing a lot of heavy lifting for your argument.
Nobody is banning the youth from accessing wikipedia or a library or minecraft.
And if a young person really wants to watch at porn, torrenting/piracy will always be there without age verification.
Speaking of minecraft and circumvention, do you remember the uncensored library map? https://www.techdirt.com/2020/03/19/routing-around-damage-censored-reporting-hosted-custom-built-minecraft-library/
I bet someone inclined to do so could host a pornhub mirror/proxy inside of a modded minecraft map.
But also, if the parents decide that it's part of growing up they can just give their kids access to porn.
Oh uuuh I mean, not porn, iNfOrMaTiOn.
