Why do I need root-privileges to update my package manager's package list?

I can understand why you need to enter your password for an sudo apt install daSoftware or even sudo apt upgrade: you are modifying the code that will run on your machine.
But why on apt update? You are just updating the list of available software. Why would it be a problem not to ask for the extra privilege granted by the super user mode to perform an update?

The list of software is written in protected areas (/var/lib/apt/#1) you don't have write access to. The elevated permissions are required to write into that directory where all users can read, but not write.
#1: @jordanm correctly pointed this directory out; thanks Jordan

Because everything you do with sudo requires a password by default, and there's no exception for that in your sudoers file (though you could add one via NOPASSWD if you want).
