This is a good discussion. The flipper mindset is probably localized to software tech, and maybe that mindset is required. The reason is the constant change of technology, the shifting attention span of web users, and the maturity of the field make it harder to build a "normal" sustainable business. So, most people take the path with less friction: build something that gets enough attention to sell, profits optional. Lack of technical depth and, hence, barriers to competition are factors, too.
