Well, they're quite different. Morally, legally, whatever, the society at large assigns larger value to a human than to an animal - any animal. Plus, they didn't do anything illegally - at the time they bought it, it was legal to buy it and sell it anywhere in the world.

You're now eating meat. It's quite conceivable that there might be a future where eating meat obtained through killing animals is considered as barbaric as you are now considering ivory trade. Different time, different people.

I only told you about ivory because it was __relevant__. It's a thing you can relate to - that people did in the past, without giving it much thought. Ponzi schemes are outlawed and considered imoral - do you consider _impossible_ a future where a marketing campaign convinces people that crypto is just a form of ponzi scheme, and participating in one is not just stupid and illegal, but also imoral?
