There is no theft if you don't have a concept of ownership or value wealth.
See e.g. the punishments used by members of the Haudenosaunee Confederacy for theft.
Well it doesn't look too bad:
Theft [in Haudenosaunee/Iroquois society] was comparatively rare, for land was the property of the community, surplus food was commonly shared with needier neighbors, and the long bark dwelling belonged to the maternal family, and the personal property like the tools and weapons of the men, the household goods and utensils of the women, were so easily replaced that they possessed little value. Practically the only objects open to theft were the strings of wampum beads that served both as ornaments and currency; but such was the value the community of spirit of the Iroquoians, so little did they esteem individual wealth, that a multitude of beads brought neither honor nor profit except so far as it gave the owner an opportunity to display his liberality by lavish contributions to the public coffers.

[In Tsalagi/Cherokee society] Rather than coercion and punishment, social sanctions like ridicule, withdrawal, and ostracism, were used to bring wrongdoers and non-conformists back into harmony with the community.*
