I had to resist the urge to break into uncontrollable laughter when you compared living in your car to saving a baby from a burning building. Since this is a throwaway I strongly suspect you are your own cheerleader. Let me see if I can take you down a peg.
A man who chooses to live in his own car instead of taking a servile job is presumably still in need of food to sustain him. You are basically glorifying living off other people instead of working for a living.
It's a ridiculous comparison, given in response to the ridiculous assertion that homelessness is a privilege.
At the end of the day, at some point someone says "these working conditions are too shitty and I'd rather go look for something else". That person sets a lower bound on working conditions for people who aren't able to leave so easily. Saying "how dare you not work for a pittance with all the other poor buggers trapped on a wage where saving is impossible" is blind; calling it privilege is wilful stupidity.
