Indeed, if you read the great-great parent comment, we are not talking about a device for Bear Grylls to be used in the wilderness.
Activation is an annoying concept, but except crashes like yours, a device will work just fine without a machine with iTunes nearby.
In this particular anecdote, the nearest Apple store would have been in San Diego, 3200 miles away. The nearest internet connected computer capable of downloading iTunes was a mere 150 miles away in Buenaventura, a 2 hour motor launch, followed by a (weekly) night boat from the village I was in.
It was meant to illustrate that sometimes you take your mobile devices away from civilization. Suggesting that the solution is to bring them back to civilization sort of misses that point.

If you take your dell laptop back to PC World, don't expect much.
It somehow knows to do this at the moment you're furthest from being able to find a computer with iTunes. My iPod Touch did it when I was on the Pacific coast of Colombia for a month (note the complete absence of roads and towns along said coast).
Getting to a place where I could listen to music again involved an overnight trip on a cargo boat through pirate-infested waters.
But I suspect that was an edge case that Apple didn't have in mind when they designed that feature.
