That's also completely controlled by where you live. There are a few places on Earth naturally abundant enough(and with climate friendly enough) to support a population with less than 40 hours per week per person, but I'd bet most of the planet doesn't fall into that category.
We can do it more or less anywhere, it's just a question of population density. A tribe that needs a few hundred square miles of tundra could live as well off of a few dozen acres of tropical forest. Here's a bit of trivia for you-- the most "abundant" place on the planet, the place once home to the highest density of exclusively foraging peoples, is the area now known as Northern California.
Yes, it's definitely doable--I'm not arguing with history. I'm arguing with this
>they didn't work anywhere close to 40 hours a week, and spent most of the day chatting and making music
A tribe that lives in the tundra is going to have to devote a substantial portion of their time to preparing for winter. Which isn't going to allow them the vast leisure time enjoyed by African bushmen living close to the equator.
