The disagreements rise in how to measure this relative risk, and risk and return models in finance have tried, with varying degrees of success, to come up with this measure. I believe that a company's regression beta is an extremely noisy measure of its risk, and mistrust the betas reported on estimation services for that reason.
The WACC formula derives the current cost of each form of finance, starting with the risk-freerate, the expected return on equity, and the costs associated with debt financing. The required rate of return for equity (Re) is generally calculated using the Capital Asset Pricing Model (CAPM). A beta of 1.0

Thus, you and I can disagree about whether beta is a good measure of risk, but not on the principle that no matter what definition of risk you ultimately choose, riskier investments need higher hurdles than safer investments.
In my last three posts, I looked at the macro (equity risk premiums, default spreads, riskfreerates) and micro (company risk measures) that feed into the expected returns we demand on investments, and argued that these expected returns become hurdle rates for businesses, in the form of costs of equity and capital.
In short, if you don't like betas and have disdain for modern portfolio theory, your choice should not be to abandon risk measurement all together, but to come up with an alternative risk measure that is more in sync with your view of the world.
