Absolutely correct, they would be of no use. That's why some bumpers' mount to the frame is engineered to crush and any frontal impact is absorbed as the bumper is pushed back to achieve the same function of lowering force. Lot's of vehicles with mounts like this.
Given their purpose and limitations, and for me personally,
Would I buy a bumper for my Jeep based on no consideration other than if it had crush cans or not?
If the bumper I decided on didn't have crush cans, would it be a big deal, cause of concern to me?
If the bumper I wanted had optional crush cans available would I buy them?
Depends on price for the cans; $100-200-probably yes, $500-nope.
