How so? Parents and schools can collectively decide to take away the smartphones of preschoolers if keeping them safe and focused was the main priority. Like how else is a preschooler gonna get a smartphone without adult money and support? Last time I checked preschoolers can't open a checking account and a credit card.

This bs of government forcing everyone in the country to have to doxx themselves just so preschoolers can't access social media(which they will anyway since rebellious children are very resourceful on cheating the system made by tech illiterate adults), is like if prehistoric humanity were to stop using fire just because the village idiot burned his house down.
