I don't actually think your second point is correct on either a historical or practical level. Historically, humans had a lot of what would now be considered downtime, especially in certain societies. And practically, nothing actually "requires" that except for the fact that we've set up society in such a way to allow some people get to grow wildly wealthy on the backs on the labor of most of the people putting in that actual work. That's the result of a series of choices, and could absolutely be changed. Nothing "required" about it.
