Shipping eggs and shipping live chicks are totally different ball games. It's like comparing basketball to lacrosse, or football and golf, it just isn't comparable at all.
Day old chicks are magnitudes less fragile than embryonic material, so sellers are able to have guaranteed live chick arrival policies. Which still doesn't mean 100% of shipped chicks will arrive alive, just that the seller will refund the cost of any that die during shipping.
Hatching eggs on the other hand always come with a disclaimer that hatch rates are not guaranteed. Every listing I've ever seen for hatching eggs includes a warning that you are risking 0 eggs hatching. That's just the risk you take when you order hatching eggs. The best a seller can do is guarantee that the eggs will arrive unbroken. Unless stated otherwise, any refunds or replacement for non-viable eggs is purely a charitable gesture and should be considered a favor and not expected.
