You literally open the gates for mid season griefing this way.
Say you play your rival of whom you can assume his economy, can't be too bright. You set your ticket prices to max and send them to bankruptcy range.
Also with neutral court you make PR staff with spec obsolete.
I'm not saying it's optimal. But almost nothing is. Look at b3, you can have bad luck during season and you barely make it to PO because of that... then you play all your games away. Just because you lost to let's say TWT and Essec.
Sometimes life gives you lemons
