We should make spaces that are suitable for children (most of which should not be age-segregated spaces), we should tell them to stay in those spaces, and we should treat their en-masse disobedience as a policy failure.

Children are getting into debt on online gambling sites? Investigate. Suppose we find that half of children saw a betting ad and wanted to play, and a third just really like online poker: banning gambling ads and providing no-money online poker would be good interventions. "Remove computers from the public library" and "require ID verification to participate in pub bets" are not sensible interventions.
