Python has complex mechanisms to avoid depending on "whatever random stuff is in /usr/lib/python$v/site-packages" like pyenv and whatnot. Clearly that approach comes with a lot of downsides, too. Most newer languages avoid this pattern, including Rust, Zig, and probably others, and languages that don't tend to have workarounds; e.g. npm, bundle, etc. all use a "local" installation by default. And while security problems are of course still a thing, there are a lot fewer of them than in C. Even in C it's not as bad as in "buffer overflow of the week" like in the 90s. It's that argument that's 30 years out of date.
