There's nothing that prevents companies from selling insurance along state lines - as long as they comply with the insurance regulations of every state they want to sell in. See: http://theincidentaleconomist.com/wordpress/meme-busting-selling-insurance-across-state-lines-will-lower-costs/ http://theincidentaleconomist.com/wordpress/meme-busting-sel... "Selling insurance across state lines" is a misleading way of saying that companies should be allowed to sell in a state without complying with that state's regulations, just the regulations of their home state. Given the example of how this played out in other markets (e.g. credit cards), a more accurate summary would be "remove state-level insurance regulation".
