Huh? The solution to missing features is to stop using the product? My 18-months old is getting really good at several puzzles on my old iPhone. He also delete

Huh? The solution to missing features is to stop using the product? My 18-months old is getting really good at several puzzles on my old iPhone. He also deletes apps constantly, because there is no lock mechanism/parental controls. The fact that the iPhone is exclusively his to play with is irrelevant, as is its price. "Show them the money" is equally irrelevant. By definition, you cannot measure how much consumers value something that's not there. I'd love to show Apple my money but I can't magically pay for a non-offered feature.
