If you're talking about "the freedom to escape one's surroundings and move away", the book has been widely criticized for that assertion, as Graeber is extremely ideologically motivated.

If you left your tribe without being accepted into another (whether through marriage or some kinds of previous personal alliances you'd made), life would be pretty rough if you survived at all.

Sure tribes would split sometimes when they got too big or disagreements split them. But that's not about the individual level. That's akin to nation-state secession today.

There's no evidence that people were just regularly packing things up and going off and joining whatever neighboring tribe they wanted to, whenever they wanted to. And this is the type of thing where the book has come under such heavy criticism:
