So since we can’t count on all parents to properly parent their child, we’ll just infantilize the entire population and treat every single person as a child by default.

Any other solution to suggest aside the two obvious ones to use when the two obvious ones fail ?
Because face it: there are parents that don't properly parent their child and I suppose that we agree that also these child should be protected in some way.

Yeah. Again, I’m familiar with this ‘think of the children!’ line of support for fascism.

And again, I don't think that making sure that a law that already exist in the physical world is held valid also on internet is fascim.
We are not living under a fascism regime even if we are subjected to laws that ban something, be it minor accessing porn material, minors accessing alchool or adults driving while drunk or too fast.

And just as a totally coincidental side effect, the censoring tech will allow the government greater tracking of everyone.

Now, that is something we can talk about trying to solve a problem, how to check these kind of things without tracking or unecessary privacy invasion.
