Those are all excuses to justify keeping the ravens captive because of a ridiculous superstition. The only ethical thing is to not keep these birds and let ravens (and all birds for that matter) live their lives naturally in the wild. I could chain you up "just a little" and let you have a walk now and then and even feed you well and treat you nicely, but you would still be a prisoner and it would be wrong for me to do that to you.

I think we romanticize flight, because otherwise that sounds just like owning a dog or an indoor cat.

You don't cut off part of your cats' feet so they can't go too far from home.

Edit: as pointed out elsewhere, wing clipping is not permanent. That's not the point.
