As a freelance developer you don't have to build things that are profitable. You just need to build something for someone with money that they think will be profitable. I don't know how many stupid products I've built that I don't personally find to be profitable.

It's easy to find many products that are wanted by only one person. Therefore, consulting is easy. Building a startup is about finding one product that many people want, which is much more difficult.
