My home system is "1540 Jackson Ave" which is my address. The
assumption is that someone wanting to use my system can bang on the
door and ask permission. My office SSID uses the company name.

Which raises the question, if someone uses your access point without
permission are you within your rights to do whatever you please with the
packets (and their contents) you detect?

Seems fair, steal my airwaves and I'll steal your data in return.
