Right Question:
Why is my telephone any different from any of my other property. Do telemarketers have a right to trespass on my property just because the address is published.
Your Phone Number is leased you do not own it. If you have a problem with your phone don't have one. Telemarketing is a multi billion dollar industry. There are many ways to avoid the calls, Caller ID is one. If you are still bothered by calls at dinner, it's you own fault for letting it happen.
The spectrum above your house is being "trespassed" by my headlights when I drive by. The air is being "trespassed" by my sound waves when I call from the sidewalk. Those media can indeed be regulated to some extent (e.g. the FCC can prevent unwanted radio waves from reaching your house). But you have signed up for a service which allows ANY electrons to enter your house over a wire. If you don't like that service, then get a different one, for example, a cell phone.
