If all three of those are strong motivators then the government would not need to get involved with charity and welfare either - because individuals could get satisfaction from charity and providing opportunity for others by making the world a better place, improving the lives of others and gaining the personal satisfaction from helping solve a problem.
One reason I'm not giving a good chunk of my money to charity right now, is because I'm afraid.
Afraid.
I have saving, which I could give away, but cling to because they could come in handy. Could lose my job (oops, I did lose my job), and I can't count on welfare to keep my standard of living forever. Something bad could happen to me, and I may need my savings.
If I could count on a sustainable basic income, it would remove that fear. I would probably give more to charities. I'd probably be less afraid of freelance work. And I'd probably work on something actually worthwhile, such as research in programming techniques. I may even volunteer for a bit of menial physical work for a change.
