Where does he live? It makes a huge difference if he lives in a farm house in the middle of a field or if he lives in an apartment building in the middle of a a large city. If you live in such a way that the only way for me to see your network is to sit in my car in your driveway, then perhaps. However, from the comfort of my sofa in my living room i can 'see' at about a dozen different wifi networks (and by extension at least a dozen people can see my wifi network from their sofa).

That kind of changes the math a bit. I don't want a dozen people torrenting off my network, not because I'm afraid of getting in trouble, but because it degrades my ability to use my network.
