Because you need specific skills and experience, not only motivation? When you need an accountant, you don't invest in a motivated office assistant to learn accounting, you hire someone who already spent the years to do it properly, since there are many steps between a random person and an accountant and most likely none of your current employees are "almost-accountants" who are ready to take the next step. And when you need a CFO, you don't invest in a motivated accountant to learn how to do that, you hire someone who has already spent the years to do it properly, since there are many steps between an accountant and a CFO and most likely none of your current employees are "almost-CFOs" who are ready to take the next step. Startup founders hiring random "good people" without competence at the appropriate scale as their CxOs is a good way to disaster.
