Only if you desire (what some call) a technically "perfect" image!
However, it is exactly the effect the Holga photographer desires, so if you used a higher quality camera, you would have to spend an inordinate amount of time introducing optical aberrations, distortions and light leaks to the pristine image, thereby spending MUCH more time than a simple shutter snap through a coke bottle lens.
It's like arguing the "why we shoot decay" thread with a pronouncement that one should only shoot sound, intact buildings with a fine camera.
There, that aught to whip this back to the top of the thread list!
Another can of gas, Horatio!
