As a child I had unlimited time to work out how to access stuff that interested me, a lot of which was forbidden in some way, because that's the most interesting stuff!
In the process I learned about computers and eventually got a modem to access BBSes. It was exhilarating! I would have spent any amount of effort and time to access it.
I basically attribute my entire career to accessing stuff the puritans would have tried to prevent me from accessing.
Also, almost all of the porn I have came from private trackers.
I very much doubt they will be concerned with any of these rules. Things will just move more underground if that happens. And the more underground you go, the more unsavory stuff you might find.
But we all know this isn't actually about protecting children.
In a way, I hope that it ends up being a good thing because the whole clearnet should probably be nuked from orbit.
Us nerds can come up with something better. Federated, encrypted, anonymous and unblockable. It's just the spam problem that is the hard thing to solve. Maybe reputation with proof of work could work.
I'll happily leave the normies to their milquetoast, corporate, manipulated existence.
"isn't actually".
It's dual use. It is about protecting children, but also along the way these other properties happen to come along. Thing is, with enough cryptography, we could get a way that this would work, but it's too complicated, which results in you being right after all.
