Money can't buy you a sense of purpose, especially if that purpose would largely involve non-monetary aspects.

The thing, being poor doesn't buy one a sense of purpose too. Money for sure doesn't solve the issue, but it gives you all the freedom to solve it for the rest of your life.

Damn I wish I had a million so that I could just drop my job and twitch my coding and gaming streams 12/7. I can't do that.

Absolutely. Money (at least some amount, at least for most people) is necessary, but not sufficient for a fulfilled life.

I believe most people having that million wouldn't spend it to find the fulfillment in life, but would end up increasing their life style by slacking off, drugs, expensive cars and items, etc. And the million would be gone in months and you would be left with just bad habits, dopamine hangover and no idea of the further direction in life.
