> Why put any effort in making sure player locality influences the surrounding quest level, if player can go anywhere, let's put level appropriate enemy everywhere.

That's not how it works in Diablo 4, enemy scaling only comes into play if you go to an area that is naturally lower level than yours. Looking at the world map and hovering over areas shows their minimum "recommended" level, and enemies there will start at that level.

So you absolutely can go as a lvl 10 character to an area that expects you to be 40+ and get smacked down in a few hits by a basic lvl 40 minion.
