"I looked at what I think of as the food chain that led to the financial crisis, which was that you had individual consumers buying houses they couldn't afford, sold to them by realtors and property people who were competing to sell more properties at a higher price and so on. [...] I thought, hang on a second, classic economy theory tells you that a competitive marketplace is superior because competition provides a diversity of products which is good for the consumer, and it also, therefore diversifies risk. And yet, in this instance, competition has led every single one of these companies to copy each other, which had concentrated the risk. And I thought, Wow, that's interesting. That's specifically what's not supposed to happen."

This is simply expecting too much.
The core issue is that other people want different things than you. You want fair sports, they want to win. You can try to make rules but they are not 100%. The only thing that would really work is if they wanted the same thing as you.
Depends on what exactly they want. If they want to win at all costs, you're correct. But perhaps they want to win at low cost, performance enhancers have a high cost, and cognitive biases prevent them from seeing that.
