Digital Smarts - Banning Smartphones for Those Under 13?

A group in Colorado called Parents Against Underage Smartphones is looking into putting a ballot initiative up that would require retailers to submit reports to the state government verifying that they had inquired about the intended user for each smartphone sold, and fine those that repeatedly sell phones to be used by young children and preteens. Many critics understand the reasoning behind the proposed law, but think it oversteps the government's role into private family life. What’s your opinion?
