So because you don't take this as seriously as others, you feel that everyone should be brought down to a sensible level of seriousness...?
Let's say that qualifying was on the day of the event; a 10 minute session or whatever. If someone did 200+ laps of practice beforehand they're more than likely to be able to perform as well as they did in their 200 practice laps. And you can't limit how much practice people can do; that would be silly.
It doesn't make a difference whether the laps are done on the quali server or on any other server or offline. Having the quali server there is good for people who are done qualifying and want to do some full stints or whatever.
