You buy a digital claim to own a non-scarce jpeg, that anyone can copy, but only you can "own". Problem is, to enforce your ownership rights you are relying on the security of whatever the underlying block chain is. And, we know that Ethereum has changed history in the past (DAO failure in 2016), and they can do it again anytime a majority of the stakeholders think it ought to be done. I think rule-of-law property rights are more robust, or simply owning bitcoin, as its just a protocol without a group of people in change.
