An adult still has to pay for that internet service, and at that point it's up to the adult in charge to implement sensible filters or protections. Libraries do it, schools do it, and I'm increasingly seeing it on flights and hotspots.

Now of course, a smart kid can bypass those filters (I did just that in HS), but kids will always find a way around whatever filter or guardrail you throw up as an obstacle if they really, really want something - just like how they'll pay a homeless person money to buy them booze or R-rated movie tickets or porno mags back in the day, or using fake IDs to get into bars and clubs.

But 99% of kids will be deterred simply by the existence of it. And that's enough.
