You cannot afford this in the era of the modern regulatory state. You need projections showing you will be in the black in 5-10 to get financing most of the time. Anything you get after that is just gravy.

There are some exceptions for government intertwined industry (energy, farming, etc) but even then the long term risk is pooled and counter-balanced through financialization so nobody is holding the bag the whole time.
