Very valid points, and I suppose I should clarify that my hypothetical money flinging would have been preceded by more in-depth research and making sure they had some relatively good idea of how to make it happen, etc. And I completely agree that their presentation is oversimplified.

Still, the more hardware manufacturing improves the more it becomes possible to have reasonably good hardware in small sizes. Granted, lately the fad has been to use that extra smallness to make pancake/crepe phones which are at least in my book annoyingly wide and annoyingly flat, but I suspect that trend will only go so far.
