If you had the money to retire at 30, your savings would be invested and on an average year your earnings would cover your expenses. You would have health insurance, so no worries there. The only catch is that you would have to keep your expenses at 65% of what you spend right now. Would you take it, or would you rather work a few more years for a better lifestyle and financial security?
In this hypothetical circumstance described by OP, you don’t have $80m on which to live frugally travelling the world pursuing your interest in photography.
For most people, living on 65% of their current earnings would mean a serious curtailment of their current activities. A subsistence if you will.
Besides which, most hobbies aren’t really satisfying in a way that can nourish the soul, certainly not the ones you can do at home for little or no cost anyway.
