See my other reply. The Realtors in the firm that I manage don't do cold calls, but we do cultivate personal contacts and rely on word-of-mouth referrals. If we are told of somebody that one of our contacts knows that might be interested in buying or selling, then we would want to call them, introduce ourselves to them, and explore with them if there is any possibility of our being of help to them. If you essentially outlaw even that type of calling, then what you are leaving businesses like mine with is no alternative but to bombard your mailboxes with junk mail and blanket the airwaves, newspapers, and signboards with advertising. And that will assure that instead of a highly competitive marketplace, you will drive out all except one or two corporate giants, and the cost of selling a home will increase substantially. Again, where is the "consumer protection" in all of this?
