Tinned food is very far from indestructible.
Sufficient heat will burst the cans. Sufficient weight will break the cans. Even falling from a shelf can dent cans enough to break their integrity. Freezing temperatures can also burst the cans, from within as the contents expand. High humidity or exposure to water can cause corrosion. Large temperature swings, even within ranges humans can tolerate, can cause seams to break. And, while canned food iff stored properly is generally safe to eat long past its best-by dates, nutrient values go down over time even if the cans have remained intact.
