Speak for yourself. I want to do nothing and have no interest in contributing anything to society. If I won the lottery tomorrow I’d guarantee a net negative for society.
But I bet within less than a year you'd be doing art and coding projects, volunteer to a charity (because you are getting paid regardless!) or going back to school/self teaching yourself stuff.
The closest comparison I can give to this feeling is how teenagers manage to make awesome projects because they have the time and motivation to work on stuff, without worrying with the financial aspect of their lives.
