The more important difference in my opinion is that Facebook already has an access gate.
Unlike most search engines or the internet itself, Facebook requires an account and asks for your age to use most of their features.
Where I wouldn't want to see the internet put behind some universal age verification, I would expect Facebook to act reasonably with regards to content children see given that they already know how old you claimed to be.
