But a thing that you wrote the same a few times isn't something that's definitively required to be the same, it's something that happens to be the same right now. You can often clean things up by factoring out that duplication, but needing to add a bunch of parameters to the resulting function is probably a sign that you're trying to combine things that aren't the same and shouldn't be coupled together.
Where I'm saying you absolutely shouldn't copy paste is where there's a business or technical requirement for something to be calculated/processed/displayed exactly a certain way in several contexts. You don't want to let those drift apart accidentally, though you certainly might decouple them later if that requirement changes.
