UBI seems great as someone pursuing the FIRE route. Let's say I need $80k for a comfortable lifestyle in my Midwest town. At a 4% safe withdrawal rate, I would need to save $2M to achieve that. But add in a $20k UBI for my wife and I and suddenly our required FI number is only $1M. Now that's not factoring in changes to tax rates, but it seems very unlikely that increased taxes would eat up all of it. I could see UBI saving me $500k+ in cost of retirement. Then add on to it you now have the insurance of a floor under which your income will never fall, even if the market crashes horribly.
