It seems fair enough.
Does the FIRE community really consider 3% to be the gold standard? Bogleheads likes 3%, if not lower, and Financial Sumo advocates 1% or something, but 4% (Trinity, Bengen, Kitces, etc.) seems to be the standard.
Something was off with the DCA explanation, too.
If more and more people started to FIRE, I expect corporations would adjust. They'd offer better work/life balance, more part-time, etc. We adjusted from 60+ hours/week in the 1800s to 40 now. There's no reason it can't be lower.
