I don't think it's a given that full permissions on a device imply that a user will be able to run their device the way they want to. Permissions are necessary but insufficient. The other part is knowledge and ability. With permission but not knowledge, the user experience gets worse not better.
No, but the user will be able to run their device in the way that they want to. I'm not supporting no protections, but you should always let the user override those protections at the end of the day if they so choose.
