Artifacts, like "arrow heads" or projectile points, are not renewable resources. When they are taken away from a site we lose all info relating the two, and in some cases can no longer date the site or say anything substantive about the past in that location.

Given that Deckers et al. 2018, pp 323-4 suggest 'no cultural damage' is done when artefact hunting removes items from ploughsoil, I think the concept of 'surface sites' needs explaining in some circles in professional/academic archaeology too.
