Having the things you mentioned (or easy access to them) only frees you up to see if you are happy and to figure out what will make you happy if you aren't. They don't, by themselves, make you happy.
Disagree. If I couldn't afford to live in a safe neighborhood and was always worried about my kid getting shot on the way home from school I would be miserable and stressed out.
Moving to an area with a lower violent crime rate would objectively make me happier.
If I was wealthy enough I could simply not work, and spend my days hanging out with my daughter and spouse. That would objectively make me happier.
