Do you not picture a distinction between a landline (non-cordless) phone and wireless internet?

By 'trivial' to tap into, you mean I'd have to physically cut your line somewhere and attach a listening device, right? It seems very reasonable to expect privacy on a physical point to point wire.

With Wifi, if you're my neighbor, I need to sit at home with my computer and your photons come straight to my antenna. It's like you're giving them to me. I don't see the similarities.
