Great article! There's been a lot of discussion in the community recently about the general expectation that everything in WordPress will be free or cheap, from theme and plugin pricing to developer rates. The sheepish "Am I really a business?" feeling seems closely related.

In my opinion the more we're able to stick our chest out and say, "I built this, it solves a pain point for a large audience, and it costs money: It's a business" (or a startup), the more we can shake off the sheepish/cheapish attitude and aura that get in the way of our work as WordPress professionals.
