Because when it is to actually get paid work done, all the bloat adds up and that 3 days upfront could shave weeks/months of your yearly tasks. XKCD has a topic abut how much time you can spend on a problem before effort outweighs productivity gains. If the tasks are daily or hourly you can actually spend a lot of time automating for payback

And note this is one instance of task, imagine a team of people all using your code to do the task, and you get a quicker ROI or you can multiply dev time by people

You can write perfectly well structured and maintainable code in Python and still be more productive than in other languages.

That also goes to show why to not waste 3 days to shave 2 seconds off a program that gets run once a week.
