So where do you draw the line? Should there be one computer company, one car company, one airplane company, one movie studio, one agriculture company, etc? That's the natural conclusion of your logic. Either you add a bunch of special cases (that doesn't work in X, Y, and Z industries, or in country A's economy or culture), or your logic is flawed. And if you add special cases, you have to justify them.

So either you think that there really should be one company per thing (for whatever definition of thing), in which case that's a whole 'nother ballgame, or your theory is logically inconsistent.
