This has already been proved by themeforest.net years ago with their admin templates

True. Clearly their time is divided into doing so many of those themes.

Instead, if they did a (or a few) authoritative themes with compass css with such good documentation as bootstrap and their theme works at all resolutions, I'm sure people will use that one too.

Themeforest is a marketplace. They make money no matter which one you buy.
