Many of the costal socities of the southeastern united states became quite sedentary actually. All while still relying on wild food sources.

Like I said we have ethnographic evidence for this.

You are still making a good point in what these people needed for survival. Not quite sure why you felt the need to expand on the point I was agreeing with you on, but you are right those things take time.

We are disagreeing on how much time these things take. The historic accounts, ethnographic accounts, and archaeological evidence points to them having what I would classify as "a lot" of free time. Or at least more than you are assuming.

Of course these things are hard to directly quantify. We'll never truly know if these people had 2 or 6 free daylight hours a day to engage in non-survival related activities. We know they had time for arts and mound construction. Those aren't strictly survival, but human society likes to blend those lines. You don't have to build a mound or create a necklace for survival, but there may be societal obligation to do so

Also to be clear from my first comment I was talking about certain societies not all hunter gatherers
