These analogies don't work. Sending a bunch of data to a computer and receiving a bunch of data in return is in no way analogous to physically entering private property without permission. They are not the same thing, or the same order of thing, or at all comparable.
The only "real" thing about either of those 2 cases is social conventions.
Is is entirely impossible to imagine a culture where walking unbidden into private property is very normal but pinging someone electronically without a common understanding is an intrusion?
