Also, I think there are a lot of exceptions and counter examples especially in the startup world.
According to some, if you're out to build a monopoly, that's a different ball-game, and it then makes sense to steer clear of any market with competition with deep pockets (walmart) unless you've something revolutionary up your sleeve that can't be easily replicated / duplicated (amazon).
One of the most striking examples I know is facebook.com: They had fierce competition from copy-cats (vk) and other companies that had their own take on social (orkut, friendster). Some lost (path, color), others won (whatsapp, twitter), and/or are winning (tiktok).
There is always more room than one may be led to think.
