I like the article, but the author's message is complex. It does not boil down to: let your kids play on their ipad all day long. She is saying that the problem is not the ipad, which can be a wonderfully enriching part of our lives; the problem is how we use it.
I have found that it's 100% not true that limiting things always makes people want them more. The truth is more complicated and random than that.
The children I know who had interesting, exciting, creative family life when they were young, including parents who enjoyed doing loads of different fun activities- messy art work, outdoor adventures, varied and creative cooking, etc, and who also limited screens (without making them into a special highly-valued reward or treat), tend not to end up obsessed with their electronic devices.
If you love cooking, are good at it, and have a fun and relaxed attitude towards a wide variety of foods, you can bring up vegan, sugar-free children who do not crave sugar. I have seen this done.
In order to limit things like junk food and screens, which are addictive, cheap and easy , you must be a parent who genuinely enjoys the alternatives.
The problem is that it is very easy to slip into using screens as babysitters, bribes, and ways to fill up precious empty time when young children should be doing all sorts of things.
