I feel like I'm maybe missing some context here, because I've never had to install "conda Python" on any Mac ever. I had the system Python and a Homebrew-installed Python happily co-existing, and at various points have had "virtualized" Pythons installed via virtualenv or pipx. On Apple Silicon Macs there's no Python installed by default at all.

Now, I've seen an awful lot of programs written in Python that decide to force you to install them with virtualenv or pipx, but that's not Apple's doing.
