User: I'd like to install software from apt

Linux: I need to see your sudo credentials, do you have authorized access to install stuff from the most heavily monitored package manager?

User: I'd like to install software from Python pip.

Linux: Come on down!  No sudo required! BLIND TRUST IN DEV SOFTWARE!  Just flag it with "--break-system-packages" and you can DESTROY YOUR SYSTEM! 

 pipx is a good alternative because it runs at isolated environments  

 As ordinary user, you cannot instal anythig system-wide, just for you.
venv+pip also install just to isolated environment. As millions of people are doing usually. 

 Ehm...
Will pip/pip3 install as non-root uid library to system directory? Really?
What is the difference to download any piece of sw directly from github as non-root user? 

 yes pip does non-root uid without root. they justify it as it's more open and reviewed.  also that the user used sudo to install pip/python3 to begin with.

I'm not saying I agree with this, just answering your question
