Sounds like an excuse to stop yourself from starting and continue pointing fingers at someone else. Also, sounds like you think they are somehow special and unique and have powers that you don’t.

It doesn’t cost anything to hedge against risk and make a plan for potential failure, and you certainly don’t need to be a billionaire to do it.
