Yup... it's just that inspecting the item also has a cost, which may lead to the item not being profitable to resell anymore, in which case it is destroyed without inspection. Or it's the individual employees who choose to play it safe and prefer to destroy an item rather than risk customer complaints if it get resold in less-than-mint condition.

Inspection is quite cheap. In cases where it's not worth returning+inspecting, Amazon generally tells you to just keep the item as well as the refund. That's generally the case with items under $10. If you abuse this, your account will ultimately be banned. If Amazon's bothering to accept the return in the first place, it's because it's worth inspecting.

Also, individual employees don't get to "play it safe" in either direction. There are expected rates for grading returned items. An employee will be penalized or lose their job for wrongly marking resellable items as non-resellable (destroy), just as much as the opposite.
