From the essay: "And since risk is usually proportionate to reward, if you can afford to take more risk you should."
I think I understand the intent of what you're saying here, but it could also be read to mean that you can increase your reward simply by taking on more risk. It might help to clarify that whenever a market isn't perfectly efficient (which is apparently always, unless P=NP), there will be investments that carry more risk without offering a higher return (i.e. that have a negative alpha). Perhaps it's better to state that as the potential reward (or return) of an investment increases, you can tolerate more risk.
