> Accounting for time value of money, that's just pushed out my retirement date by 3 more months
You account for the time value of money, but not for the time value of time.
A week right now is worth more than a week 30 years from now. 30 years from now, your life might have changed beyond all recognition, or you might be dead.
Reasonable people can disagree over how to discount future freedom-from-work vs present freedom-from-work.

That said, I'm still largely in agreement with you. While there are a myriad ways to make more money, there's no way to make more time.
