It's not an operational short cut, though. For almost all of human history, it's been a practical reality. Even today for almost everyone, almost all of the time, it's still a practical reality.
When people treat the earth as flat, they're not taking a "shortcut". They're operating in the most natural, intuitive way. And it's effective, too.
Very few people in the history of mankind have ever been in a position where they were required to add any operational complexity to the equation. And even they could dispense with the complexity, almost all of the time.
Well, if you don't get outdoors much, never travel, and never communicate with people elsewhere in the world, then perhaps yes.
But if you want to understand why the sun rises and sets, why there are tides and seasons, and have an idea of what to expect from weather systems, then you need to know that Earth is round.
And if you travel by sea or air, even long distances over land, or if you want to communicate across time-zones, it is absolutely essential to know.
