Speaking your native language and walking are never taught, but everyone learns both.

Nearly every student wants an iPhone. Once they receive the phone, virtually all will quickly learn how to use it. Kids naturally learn about something they perceive as valuable.

Statists believe that school should be mandatory, otherwise students won't learn. Therefore, the iPhone must be demonized:

"iPhones are bad for kids." "It's an addiction."

The alternative is to admit that mandatory schooling is not needed.
