If you're going to dodge discussing the vast amounts of work people do for a paycheck we have nothing to disagree over.
I agree people will still want to do things when society has fully automated away paychecks. That is why I look forward to the elimination of exchanging labor for monetary reward. Let people freely pursue those passions you outline, a paycheck adds nothing in a world where automation provides such people with not only survival, but ample surplus and innovation.
