That's not very empathetic. If you were brought up with no formal education, little access to information outside of your sphere, and you knew most people that lived around you on a first name basis, you too would be as distrusting of strangers.
For all you know they could be trying to poison you to steal your land. To you their stuff might be worthless (a point you made abundantly clear) but to them that stuff is their entire livelihood and everything they have worked for. Something they might wish to pass down to their kids.
