> Where does autonomy end and the right of the government to intrude into your private life begin

I think there are really three questions bundled in there:

1. At what point is it not really free-will anymore, and more like your brain being hacked?

2. At what point can the government step in to rescue you from #1?

3. At what point can the government step in to defend others from what you do, voluntarily or otherwise?
