The danger of rejecting individual sovereignty is that if we belong to anyone who does not actively and truly desire our good, we will be abused. The reason autonomy feels safe is that we think we can trust ourselves to look out for our own well-being, whereas others will always look out for their own well-being over and against ours, to some extent or another. I know that I will take care of myself, but if I submit to your authority, I expect that eventually, despite even your best intentions, you will use me in harmful ways to benefit yourself.
