Wheels aren’t useful for primitive societies moving 10 ton stone pillars. Assuming you define them as large round objects with an axle between them. Placing various objects beneath them to reduce friction is, but it’s not actually needed either if you have enough manpower.

Metal tools would have been helpful but aren’t needed. We have many examples of actual stone tools used to shape similar objects. Ex: https://www.archaeology.org/news/6891-180813-easter-island-t...

Suggesting that hunter gathers can get together and do large works together is perfectly reasonable. Some Native Americans on the east coast did massive scale forestry without setting down in one place. This effort was rewarded because they would cycle through areas repeatedly. It wasn’t agriculture but something of an in between activity and was viable as other nearby cultures did practice farming.

Hunter gathering is migratory because they use up local resources faster than they replenish. But the rate this happens depends on natural abundance. It’s similar to why Texas cattle farmers need a lot more land to support a herd than east coast farmers assuming neither are supplementing their diets with feed.
