On paper it sounds nice.
However, I do think that eustress is needed, the problem-less life is
boring which just causes evolutionary panic. There will never be a lack
of problems. Buddhism: Dukkha: Life is suffering!
Take a prison. No problem to survival, will get fed food and has nothing to do = no problems Desire freedom, but why? It just leads to problems. He has a structured, threatless life, and doesn't need to find a job to maintain food and survival.
