One example off the top of my head: It used to be (may still be) the case that you needed admin rights to install and run the Windows Subsystem for Linux. Sure, you might not need this to do your job, but IT is not really in a position to decide that. It could be that WSL greatly increases your productivity.
Precisely! And then they'll get it wrong (or worse still say they won't do it the way you ask even though you will know better why those choices are needed!)
