If your friends can play your games at any time, it means that the game is not tied to a disc, it is tied to your account. That makes it more like Steam. How does one sell a used Steam game? The answer (for all current digital services) is that you don't- there is no used market for any game that requires Steam or Origin or any other digital service.
Microsoft wanted to change that. But in order to implement something resembling used games, you have to remove access to the game when someone sells their copy. And the only way to do that is to have the console verify licenses. The easy way to implement that is with a license check every time you start the game. Microsoft tried to be nicer than that by only checking once every 24-hours so you didn't always have to be online.
