Even though it still feels weird I can see why they did it: since the game is not linear at all (I think you can even do the first 3 acts in any order) compared to other Diablo games (didn't play 3) they kinda need to do this so you don't breeze through zones. It also helps when playing with under/over leveled friends since they just use the same system to prevent you from rushing them.
Personally I prefer linear narrative and gameplay for Diablo (it's like making linear games is a sin nowadays) but it's probably a wise choice given other design choices? Or at least understandable. It allows them to send you back and forth across regions and still present a challenge.
Anyways: I'm liking D4 (I'm surprised to say this of a Blizzard game in 2023) so not the worst design ever.
Level scaling isn't necessary for a nonlinear game. Plenty of games have nonlinear areas and no level scaling because they have relatively flat progression curves. D4 only 'needs' level scaling because it also 'needs' to be Cookie Clicker and Lootbox Simulator with an ARPG wrapped around it, and neither of those systems work with flat progression curves.
By not making level 70s cut through level 15 enemies like butter. If your level 70 is only 50% stronger than a level 15, if the enemies were challenging for a level 15, they won't be trivial for the level 70.
Thinking about it more, one cool thing about level scaling is I can play with my friends at whatever level they are. It doesn't really matter for the endgame at all, but when you're leveling up early on it is pretty nice.
