Why age a whole rib section instead of a single steak at home?

Answer: Less sacrificed surface

Deeper flavor soaking — No. Aging does not work like a marinade soaking flavor from the outside into the center. The advantage of a large rib section is geometry: the crust forms on surfaces, while the interior remains edible. A thin steak has so much surface relative to its center that trimming the rind can remove a painful share of the food.

Center-first air exposure — Almost the reverse. Dry aging works from exposed surfaces inward; air does not magically reach the center first. That is why butchers age carcasses, primals, or subprimals rather than thin finished steaks. The inside is protected while enzymes work throughout the muscle and the outside becomes the sacrificial rind.

Less sacrificed surface ✓ — Right. A whole rib section has a lower surface-to-interior ratio than a single steak, so the dry crust consumes a smaller share of the final food. The industry reports describe aging carcasses, primals, or subprimals and then trimming dried, discolored lean and fat before cutting steaks. This is the hidden math: the same rind is deliciously useful on a big cut and ruinously wasteful on a small one.
