You don't. The whole point of sudo is that it gives you fine-grained control over the privileges of each user.
sudo, is used to run as root. The point is to allow the user to do a quick operation with root permissions, then go back to running as a normal user. It doesn't "give you fine-grained control over the privileges of each user."
Frankly, I have no idea why so many idiots think they have to take each and every call right away. I see no problem with letting a call/text go to voicemail and getting back to them on MY schedule.
I'm generally like you, but don't make the assumption that everyone falls into your use case. Some people may have jobs where they need to be completely reachable at times. They may be taking care of a sick relative, and need to be reached in case of an emergency. What works for you and me may not work for everyone, and that doesn't make them idiots.
