the people who would opt in aren't likely to be the problem. The problem with your pickpocket example is that you lose something when someone picks your pocket, but you lose nothing when someone checks to see what ports are open.
In fact, that's something that's already happening all the time anyway. The only difference is that in this case the person checking for your failures to secure your devices will notify you of the problem instead of exploiting your devices like everyone else will (assuming that they haven't already).
This should not only help people secure their devices, but it should also make the internet a better place for everybody.
