Yes, I agree it doesn't fit into the standard definition of "FU money". And how much you'd need certainly depends on the job market for your specialty and location. But what I'm describing shouldn't be the "Lose your home" buffer. This is on top of that rainy-day fund, and saved up specifically so that you have that flexibility to be between jobs for a bit without having to snap up the first mediocre opportunity that comes your way - whether it's because you left voluntarily, you got fired/downsized, or the company you worked for just plain went under.
