Ad naturam

if nature is unchanging and norms are grounded in nature, does this make norms unchangable?
No, because you can make any counter-claim that is also grounded in nature, as natural orders are vast 
this makes the appeal to nature merely a tool for visualization/better understanding of tings, as its authority is very weak due to being one of millions of natural orders 
the link between nature and norm is about the general connection between norms and order (norms need baseline order), not specific cases of norms and order
