Early Valve coasted on the money Gabe Newell personally made as a senior Microsoft executive, so if you want to emulate that Valve then you'll need to find 8 or 9 figures in your bank account without taking any outside investments, in order to keep the company completely untainted by shareholder influence. That's not a template most founders can follow either.
There's a timeline where startup Valve went through the standard publisher funding model instead and got pressured into releasing the "finished but not very fun" 1997 cut of Half Life, rather than taking an entire extra year (an eternity in game development cycles of that era) to overhaul the whole game at their leisure. Things could have gone very differently right from the start.
You're saying that this organization doesn't lead to success, but because they accidentally have a successful money maker, now they can run like this?
I think there is disconnect here. There are successful companies that can operate like this, because this is a good way to get to success.
