I agree with the statement that venvs are usable and fine. However, they do not come without their pitfalls in the greater picture of development and deployment of python software.

It very often not as simple as going to your target system, cloning the repo and running a single line command that gives you the running software. This is what e.g. Rust's cargo would do.

The problem with python venvs is that when problems occur, they require a lot of deep knowledge very fast and that deep knowledge will not be available to the typical beginner. Even I as a decade long python dev will occasionally encounter stuff that takes longer to resolve than needed.
