It really doesn't work that way, for several reasons.
First, you can't predict what will happen with the economy vis-a-vis your investments and cost-of-living. Sure there are rules of thumb, but depending your age and the current situation, assumptions like "I can perpetually do a 4% drawdown" may or may not be reliable.
Second, the ability to say FU to everyone is not a black and white decision. Perhaps you value earning more to live a higher lifestyle in the short-term, with some optionality to say FU if things go sideways. Other people might have been burnt and would rather live a life of poverty than be forced to capitulate to The Man one more time. In the immortal words of Lawrence from Office Space: "you don't need a million dollars to do nothing". Most people probably fall somewhere in between.
And last but not least, declaring financial independence raises new existential questions which people may not be ready to answer. Having a job gives a baseline social connection and sense of communal utility. To actually declare financial independence poses a risk of alienation, which may have no upside once the immediate threat of short-term dependence on one's employer is removed.
