There’s no real reason not to use them, we’ve often had to use some sort of “reset style” to make browsers do what we want. Notably, Eric Meyer had a great reset.css stylesheet, thing was a great way of reducing CSS inconsistencies between browsers.

If you’d like to learn more about the debate about “universal selectors”, there’s a plethora of articles about it. Here’s one, considerably older but still pretty relevant: https://www.paulirish.com/2012/box-sizing-border-box-ftw/
