You don't have to write functions. Have you ever seen a 10,000 line code that was just a single function -- I have. It also had nested if statements 5 levels deep to handle all sorts of logic with lots of duplication. It was unmaintainable. Yet it did meaningful work and it could have been refactored to a fraction of the size and do the same work. But, to be honest, when I had to fix it I just went it and fixed in the 20 places that needed changing because it was impossible to follow. You like good abstractions and you hate bad abstractions. I couldn't agree with that more.
