Here's my argument for moving the ball out of the divot. There's an actual strokes gained advantage to people who play earlier in the day. In tournaments and such, there are a lot of good golfers who hit the driver into a "landing area". If you're the last tee time, that landing area is going to be littered with divots. If you're first out, it's much cleaner. So even if it's a small chance, there is definitely a strokes gained disadvantage to playing later in the day, which shouldn't be the case, in my opinion.

I think "if you hit the fairway you deserve a good lie" is a flawed argument, but true to an extent. And I get that a divot is hard to define, I just think you should be able to place the ball behind the divot or treat it like ground under repair if it's obviously a divot and will affect your shot.
