Fighting for market share and making infinitesimal margins across a large market share is the relatively easy and obvious way to do things, and it involves relatively easy and obvious processes of copying/iteration. You would think so, but while WalMart has proven that WalMart can do it in retailing, many other businesses have proven that they can't. So in the end I agree that simply proving such-and-such is possible is not a recipe for any old company doing it.
