Yes, a method of only allowing the low res preview versions of artwork to be available to non owners would go a long way to protecting pieces up to a certain point.
I hadn't seen OVR before, I'm sure there will be many such ideas in time - especially as the cost of minting NFTs reaches zero. Let's hope we don't reach a point where there is a 'lifechain' owned by Bill Gates, where everyone gets their own NFT at birth! :(
The possibilities are definitely infinite seemingly🏴☠️😄
