Isn't this just survivor bias, though? How many startups out there really believe and still fail hard? It's very easy to look at Stripe and say "they succeeded because of X", when in reality they succeeded because of a wide variety of factors.
Well, as long as you take OP's article as a reflection on one of those factors then all is well. The problem becomes that many people want to fixate on a particular thing as their elevator to success.
