Cooking Pot & Diving Platform 100 HP?

[MagicPuncher 29]

I've noticed that the cooking pot and the diving platform both only have 100 HP. Compared to something like a smithy that I think has 7500. Is this an oversight or is there some gameplay reason for this? Seems silly. And it's very annoying because I can't keep either for more than one play session because they are constantly being destroyed by crocs. The cooking pot is fairly cheap, but the diving platform isn't.
