We do have a very strong law, the TCPA, that prohibits robocalls to cell phones without prior consent, with a private right of action and a $500-$1,500 _per violation_ (per call at least) penalty. It won't do you much good against scammers, but against actual businesses with assets that could be seized if necessary, it's awesome. (I personally sued a debt collector in small claims court for wrong number robocalls to my cell phone, and settled for the entire amount I was asking, $500 per call.)
