personally i fail to see difference between --user pip install and an always activated default venv
There are three main benefits to virtual environments
The difference is more pronounced when you have multiple environments. Even if you're only ever using one environment, though, there are similar benefits. If you have Python tools (e.g. poetry/pdm, tox/nox, black etc) installed into the same environment, you eventually will run into the scenario where you cannot update your libraries because one of the packages imposes an upper-bound on the version Even though upper limits are not best practice in Python, they still exist in the wild, and can cause these problems. Worse, you can end up with two packages with incompatible version constraints (e.g. scipy wants a newer numpy than some other library). Virtual/Conda environments avoid this by allowing you to separate distinct packages into their own environments.
Related to this is pipx, which lets you install Python "applications" (libraries that you're not really expected to import from Python, e.g. pip or black) in their own separate environments, but launch them without activating the env.
Sometimes you can break your environment, especially when using pip directly instead of a project manager like pdm or poetry. Virtual environments make this less problematic - you can easily delete and recreate the environment, and only have to re-install those packages which were installed in that particular environment.
With Conda environments (or virtualenvs if you use something like pyenv), you can install a different version of Python to that of your system. This is generally useful.
