Basically what this article is talking about are two breeds of entrepreneurs:
1. Lifestyle business guys like the ones featured in the article
2. Big exit guys who are after the Forbes cover, the big IPO / acquisition, the VC funding, etc...
There's merit to both styles of entrpreneurship; style #2 obviously brings with it a lot more stakeholders (employees, investors, etc...) and therefore a lot more responsibility and accountability on the part of the entrepreneurs / founders, but the potential rewards reflect that.
Style #1 doesn't have all of the fame and glory, the 8-9 figure exits, but it creates a self-owned source of income which can be really liberating. The trick with a lifestyle business is to make your operation lean enough so you don't have to hire a tremendous number of people to run the business.
