How is this any less meaningful than any other use case? Is downloading a distro to play video games ok? To shitpost on social media? To watch clickbait videos on youtube? Why is this in particular a bad use of resources?

The other commenter already answers your quest, but I will just point out that python doesn’t come included “on Linux”. It just happens to be a dependency of so much stuff that some other packages is going to pull it in. A minimal distro which doesn’t include programs written in python will probably not have python installed at all.
