I've never used a language where space indentation was used over curly brackets. So question for those who have... When doing so, wouldn't copying and pasting code around potentially cause a lot of accidental issues? Are there some negatives and side effects of the indentation style? Just curious.
If you copy and paste code irrespective of bracket position, you will have the same problems. It turns out not to be an issue.
A big positive of using indentation is that it enforces a visual indication of scope vs. languages where culturally it is normal to find code with lots of giant one-liners and braces on one line.
But overall, you just get used to it and don't notice it. Everyone who yells about languages that use indentation is bikeshedding in the worst way.
