Kids will always find ways around regulation. Look at cigarettes, vapes, alcohol, weed; they will just get it from their dealers. Pornography? I expect something like: download a Torrent, get it from a classmate, share HardDrives in school, get it through an older brother.
It’s just defence in depth and wholly appropriate for it to be imperfect
And bootleggers will always bootleg, and smugglers will always smuggle. For that matter, murderers will find ways to murder.
Shall we just abolish all laws? None of them have any effect whatsoever, if they are even slightly imperfect... by your rule.

And porn companies should always be held responsible for not doing their due diligence and freely distributing porn to minors. Which is already illegal in teh US and most places.
