Volatility adds a real time value of money on top of nominal interest rates.

How does this work? (I thought volatility mainly affected the value of options, not the underlying cash flows?)

Options expire and decrease in value as time passes.

A naive NPV calculation discounts a cash flow by a real discount rate:

https://www.investopedia.com/terms/n/npv.asp

when the discount rate is 0, the NPV is simply the sum of all payments in the series, so an infinite series of payments (e.g. rental income) is worth infinity

in reality, bad stuff happens: building burn down, renters leave, etc. so the right thing to do is to discount the payment stream by some risk function, particular far off payments
