Sacrificing Spine of Ish Sah?
No, that's not how that ruling is supposed to be read. Though I admit they worded it poorly.

The card can be sacrificed like any other, what the ruling means is you cannot sacrifice because of the second ability, just because you want it back in hand, but you can sacrifice it to anything that would allow you to sacrifice an artefact. Doing so will cause the second ability to trigger.

The second ability doesn't allow you to sacrifice it, it doesn't give you a way to do that by itself, but it doesn't prevent you from sacrificing it either.
