What you said makes me wonder how eBay handles possible scamming (buying an NFT with someone else's paypal, for example) or returns.
I'm not sure about how they handle NFT fraudulent buyers. On other hand, there is a no return policy for every NFT listed over there[1].Regardless, I'm always happy to see big marketplaces that have a huge reach to people who might not be into crypto-related things yet. I don't shop much on eBay, but kudos to them for jumping on the train and getting NFTs in front of potential buyers who might not have otherwise known what they were!
Although I also don't use eBay, I know that eBay is known as a marketplace that many people use for physical collectables and trading cards. So, it seems that eBay fits what NFT is capable of, and they just implement it into their business.[1] https://www.ebay.com/help/policies/prohibited-restricted-items/digitally-delivered-goods-policy?id=4289&mkevt=1&mkcid=1&mkrid=711-53200-19255-0&campid=5337590774&customid=&toolid=10001
