Well, all of the item's cost goes straight to your survival, and health is indeed very cost-effective compared to getting equal AR/MR, provided that the enemy always does exactly equal amounts of physical/magical damage to you.

Usually, though, you're faced off against teams that do a lot more of one damage than the other. In that case, AR/MR can easily itemize for that particular damage to gain very cost-efficient effective health, but health-stacking doesn't differentiate between situations.

Finally, this item has zero utility. Consider what items like Force of Nature and Thornmail do, as opposed to simply letting you live longer.
