Many of those tools have important functions other than dependency isolation. Pyenv is perhaps the only tool mentioned that can be replaced by docker. However, pyenv has a marginal usability advantage over docker. You can set a python version or virtualenv to activate automatically in a project folder - no need to start a container.

Poetry is primarily a packager. Pipx installs python scripts like gita, poetry, youtube-dl etc as user commands. They cannot be replaced by docker.

Finally, I never had a good development experience inside a docker container. Pyenv, pipx and poetry play much nicer with the system development tools and give a better development experience.
