I haven’t listed anything for sale here either, but it seems like something that works for some folks.
I don’t have a problem selling stuff in person, but I can establish a level of confidence when I’m talking with a customer face-to-face that I’ll get paid up front, not hoping for payment when I deliver the product.
Since this is a “trustless” environment, that gives me pause. Should I trust someone I’ll never meet, never talk with on the phone, and don’t even know their actual name, to pay me in exchange for my work?
