If this hypothetical person doesn't realize that he or she might need some savings to cover family expenses while devoting all or most of their time to a project that isn't generating revenue yet, I am skeptical of that person's ability to successfully start or run a business. Just me? Additionally if someone is wary of losing their great consulting/contracting fees to start the startup, maybe starting a startup is not for them. Or maybe they just need to plan to minimize the risk that they will be taking. Either way, this is not YC's problem to fix, imo.
