That steelman still stands on a core assumption that its both the state's responsibility and right to step in and parent on everyone's behalf.

The idea of the "nanny state" has been debated a lot, and this seems like a very literal example of that. But once some status quo is firmly entrenched, debate about it tends to die down because the majority of people no longer care enough about it.
Then frankly you haven’t seen many debates around age verification as it’s the main thing discussed every time it’s brought up
The point of having a state at all is to create a framework where people are set up to succeed.
