It's virtual golf not the PGA Tour
I think that's the point which matters:
We're supposed to play like a virtual PGA Tour. The course set-ups prove it, OLY #1 and BPB #? come into mind, both set up as Par 4s though they are Par 5s in RL regular play.
The one ball rule is another clue. Additionally it takes a possible "option point" out of the game (programming issue? speed-of-game issue (in MP games)?).
Other options you cannot take include the various dropping options when you hit water.
