(because it's that easy!)

I don't think anyone believes it is easy, but are sanctions not at least an incentive to try?

I don't see a way to change current and global versions of python

You really shouldn't be doing this. Utilities on your host rely on the system python being stable, unchanged, pinned to a very specific python version; also with exact versions for dependencies.

For example in fedora/rhel, changing the default platform-python will prevent you from using yum/dnf to apply system updates.
