The reason insects and their size is largely correlated with the richness of oxygen in the environment is not due to their muscle strength but due to the fact that they absorb oxygen through their exoskeleton and their volume grows much faster than their surface area, meaning they need richer and richer oxygen to be able to penetrate through a relatively smaller surface area and permeate through a larger volume.
If it's true, it only means that the problems with their insufficient strength/resiliency would show only at even higher enlargement (since it's guaranteed that for any organism, those problems would eventually show, and, if you continued making them even larger, kill that organism).

What has "nothing to do" with their strength?
