As an user, I want to use "sudo pip install" because packages installed in /usr (or /usr/local) are accessible without having to touch PYTHONPATH: the install directory is part of the default sys.path.
This is also true for "pip install --user", at least on the systems I'm familiar with. There are options to disable 'user site packages', but it's enabled by default.
It's more annoying for scripts - on common Linux distributions, the user scripts location ~/.local/bin is not on PATH by default.
~/.local/bin is user-writeable. If ~/.local was on PATH or by default, it could potentially preempt/modify the behavior of system libraries and binaries; which is a security risk. ~/.local/bin/bash could be wrapper script that logs commands, for example. If it's first in the path (as e.g. Homebrew does, IIRC), it's run when bare `bash` or `/usr/bin/env bash` are executed. pipsi creates isolated virtualenvs per-install which are isolated from other library installs, but each env then must be upgraded separately.
