I feel like he is more pointing out the clear mismatch of priorities. As soon as you have the mortgage requirement that bill is there and asking for money every month forever and you getting paid RIGHT NOW when that bill's over your head starts to become a dominating factor in business decisions. A lot of the arguments in the comments here have to do with this kind of problem- we keep trapping ourselves in financial instruments that require more regularity than any early business or even early-mid business can provide. Student loans are one, but so are home mortgages and so on.
I know I am trapped by this right now- the clock that takes a good chunk of my monthly net makes you risk adverse.
