I think somehow this is related to how business minded people think too. I went to a course where people learn to pitch their ideas to get funds but the basics of business simply did exist much among the technical people. One simple example (which I suspect most of the business do) is that you do all work either manually yourself or on your laptop while advise them as a resource-rich service. Only when you truly can not handle the demand then you may 'scale up' and turn your business into 'real' business. And there are plenty of tricks like this (as legally as possible).
