I generally agree with the OP. lets compare basses to new cars.
If you test drive a new car right of the lot and the alignment was pulling to the left, and it was obviously misfiring on at most 5 of its 6 cylinders.
Why, you would say internally "this car is a piece of cr*p im not buying it!".
I havent tried a new Fender in years. Schecter seem to actually set up their basses splendidly- and Ibanez is up and down...
Some of the ownership is on the retail store- the assistant manager of the bass dept. would sell more basses if he or she performed a butter bass setup on each one instead of pining for that GC commission check!
Car alignment doesn't tend to change with the temperature or humidity either.
