If you're happy with a frugal life, then your 'little residual income' effectively IS fuck you money. Fuck you money doesn't have to be hundreds of millions of dollars, unless you want to support a wealthy/extravagant lifestyle. Then again, maybe you want an extravagant lifestyle and your own submarine. That's not any better or worse in itself than just wanting a frugal life.
