Yes, this was always the argument given in support of the monopoly Microsoft Windows used to have on commodity computer operating systems. Some proposed that having only one platform choice was more economically efficient for the industry as a whole. I don't think Apple was really on board with this idea back then.
I do not think that requiring all computers have only one display resolution for the convenience of software developers ends up being a winning strategy in the long run. It may be a winning strategy for Apple's business of course, at least until Apple decides to do an iPad or a "retina display" or for whatever other reason decides that a different form factor is in their own interest.
