I'm fine with shutting schools. And restaurants and bars. And even airports and cruise ships.

The biggest *carriers* were the millions of people traveling on planes, trains and cruise ships crossing between countries (and state lines), who ended up at music venues, amusement parks, pubs, bars, restaurants and tourist traps. That includes community transmission. The UK doesn't have special immunity.
Exactly my point. The purpose is to stop its spread - to do that you need people to stay at home, not to send children to stay with their grandparents for their parents go to work, infecting the grandparents who are vulnerable to the virus.

Adults are and were the big carriers and the elderly are the most vulnerable. So shutting down schools is helpful so long as you do precautions FIRST.
