What gives you a right to trespass on their right to earn a living on the system their efforts and hard work built. Industry built the phone system, not tidy-diaper thinking and intolerant petualance. You even have a right to not have a phone at all. You can turn your phone off. You can screen your calls, you can get an unlisted number and be serious about not giving it out. You can teach your kids to delete the hangups, though most telemarketers don't leave those. Why should they have to turn off their livlihood because you overreact, or because big government promises to scratch your itch. I wouldn't do it if I were you. You will no doubt be sorry some day for it, and you will most likely get what you deserve, whatever it is, but don't count on actually wanting it when it arrives.
Property rights I'm familiar with. The right to earn a living? Never heard of that one before.
You just evaded the issue. There is no getting around the fact that the phone line inside my house is my private property. Even you admit it is.
They don't have a right to "earn a living". They have a right to try. If they fail because people post an electronic NO SOLICITORS sign on their phones, tough -- find a new line of work.
