You mentioned it and it's still inaccurate. The study gave mice everything they could ever want, in excess. This was food, space, and mates. The needs of mice are not complex. Basic income is just enough to let you sleep indoors and eat. If you were to create a utopia for people it would be fine food, entertainment, extravagant living arrangements, a complex and fulfilling social scene, opportunities for academic engagement, etc. Free food and rent is not a utopia for people by a long shot.
