There's really nothing you can compare it to. Except for air I guess... If John pays for fresh air to be pumped into his house and some of it leaks out and drifts across the street will I be stealing for breathing some of it?

They aren't really losing anything when you access it. They're just not receiving as much for a brief amount of time.

So if joe blow parks outside of your property to make a quick phone call/check email and or send a message/ whatever for 5 to 10 minutes. Is that really such a bad thing? What was stolen?? What loss does the "victim" incur? Their internet is unlimited, they have no loss and in 5 to 10 min. they're able to download once again at normal speeds or if you're not doing bandwidth heavy activities like checking your e-mail or looking up an address or imming they wont notice jack for loss.

So who are you really ripping off here? Maybe the ISP but that's it as far as I can see.
