I'm in private business. Phone solicitation was a problem for me, I solved it. I just don't expect the government to solve every problem for me. So my side is the side of people who can take of their own affairs without appealing to the nanny-state every time something isn't to their liking.
What's that make your side?
There would be nothing wrong with this or any other scheme that prevented unwanted calls of any kind, so long as the government didn't do it. It's not finding a way to prevent unwanted phone solicitation I oppose, it's all the collectivist government solutions to everything I oppose.
