While the disruptions in distribution mechanisms and increasing ease of deploying web-apps has provided the appearance of it being easy to launch your own business and make money, I'd argue that it might very well be a transitory period until bigger players with deeper pockets lock down profitable sectors.
I just can't see a long term steady-state where the market is spread so thinly that everyone can simultaneously be a business-owner serving some small collection of a few hundred customers, instead of aggregating into single, monolithic companies that serve thousands or millions.
