Currently I see NFTs as a new status symbol, but without a way to display them (ie: flex your status/wealth). However, if you think the world will move further towards the digital realm where people will spend large portions of their lives in shared virtual worlds, this problem goes away.
There will be virtual worlds where only the true owner of the NFT (can prove with digital signature) can display their artwork. It's not so different from people flexing with their skins in various games, so I don't think it's much of a stretch to imagine a virtual world where people have virtual properties, houses, businesses, etc. where they display their NFT artwork. Have a look at Decentraland for an idea of where this might be heading.
