After having given it some thought while walking to and from the parcel place, I've decided not to.
I'd feel obliged to give full details, since it involves disabling standard ease-of-use functionality, and I couldn't walk someone through making the required changes in Windows. (I could make them myself, if I had a Windows machine in front of me, but without feedback I couldn't walk someone else through it.)
My idea had been to disable the DHCP server on the wireless router. With that gone, most people will get a signal, not get an IP, and give up and go away. But it would involve manually setting IP addresses for every machine served by that router. I work that way as a matter of course, but most people rely on DHCP, even for extremely small networks.
