Think about it from when you yourselves play football.
When you play and somebody closes you down quickly, most of us here probably are not very good footballers, so when we're under pressure we just hoof the ball away as we're not good enough or composed enough to play a possession game by keeping short passes going.
So you launch it away quickly to avoid giving it away.
Short passing is for a possession game with highly skilled players who are composed enough and skilful enough to keep the ball.
It would not make sense to have short passing for lesser skilled players
