This is a horrible idea (Score -1, Redundant)

Most states already have a DNC list. It's a burden for them to process the large state-wide lists, but they must do it. This will put these companies out of business because they simply cannot process such a large list with their antiquated systems. It translates into more expensive call service centers, which means lower quality and longer hold times for consumers. At the end of the day, you've taken away jobs and hurt the economy. That's why this is a bad idea.
