It's because programmers nowadays think efficiency is a one-dimensional concept that only applies to the code. They don't think on the big picture the efficiency on the resulting binary size and build time (implied by the number of dependencies). Another thing that is ignored is the external dependency that the user would need to run the program (whether none with a native compiled binaries or a whole runtime environment to run your python program)
