Yea, I dunno. I think you're kinda making a mountain out of a molehill here. Couple things. So at least on Makersplace and I can't speak on other platforms because I'm not on there. You can see the resolution of the images. Most people, myself included are putting up print res images. When you buy the NFT you have access to that. I also don't post that resolution when I post the image on the web(wouldn't make much sense, it's typically over 50 megs). So the buyer is in fact actually getting something exclusive.

People have virtual gallery shows all the time. When you have the token, the artwork is not bound to the platform you minted it on. Sort of like I can post via PeakD, but my post is visible on many frontends. I can mint on Makersplace, but I can see my tokens in Metamask or in a CryptoVoxels gallery. So it's not a maybe they can show the artwork. That's a part of owning the NFT that's associated w the wallet address containing it. I just had a brief conversation with a company specializing in real time 3D rendering today and they're working on real time 3D photorealistic galleries. It's definitely going to be cool and this is definitely only the beginning in terms of the tech.

Still might all come crashing down in terms of prices, but this is the beginning of something big I think.
