That is a good question! How much should a person feel that they are self governed? I mean surely we have the law and constitution for a reason? But what about freedom of speech and self determination?
I personally think that every person should have some personal autonomy. I think it is extremely important to be able to stand up for your beliefs and to be able to express them as and when you please.
It is also very important to be independent and to learn to rely on oneself. The question of how far does personal autonomy extend should be queried for each individual as we are all so different and unique. Some people push the personal autonomy boundaries all the time, while others on the other hand lack personal autonomy as well as self confidence and the ability to stand up to and fight for what they believe in.
I think that everyone needs to have some personal autonomy, after all we are the ones governing ourselves, however we need to not be too overbearing in our ways so that we do not exhaust others around us or show a negative trait in our personalities so that people might feel inferior towards you.
