With other programming paradigms, you can't just knock out all the little pieces without thinking about the other pieces because the state is all tangled up. Which slows you down. Of course you can. I don't know why people think you can't write functions that don't change a global state in any programming language. Pretty much any experienced programmer does that whenever they can.
