In this context, "legitimacy" is mostly "value from popularity". This becomes clear in the collectables market. Beanie Babies are not particularly good dolls, but through marketing, they became "collectable".<p>Collectable plates used to be a thing, back when people had large cabinets with glass-fronted doors for displaying dinnerware. You can still get them on eBay. "Lot of 3 Vintage Lena Liu Country Accents Numbered Bradford Exchange 1995 Plates Pre-Owned $24.99"[1] Zero bids. There's a vast amount of stuff like that. Nobody makes much money off of it other than the manufacturers. Even they don't do that well. Warner Bros. once bought the Franklin Mint, around the time they bought AOL and Time. That didn't work out well.<p>That's what the NFT proponents are trying to replicate - mass-market collectables. With an additional "fear of missing out" component. The high-dollar one-offs are promotional items for a projected flood of bulk collectables. (If they're even real. Those hyped multi-million dollar items, if they sell at all, do not seem to be closing as legitimate arms-length transactions where real money changes hands. See the Beeple fiasco.)<p>As a store of value, NFTs are terrible. None of this stuff is very liquid. Too many different items, and no market price. You have to put the thing up for sale and wait. Wait too long, and nobody cares. This Three Stooges collectable plate [2] can be yours very cheaply. The shipping and handling is more than the price, so the transaction cost is more than it's worth.<p>At least NFTs don't have high storage costs.<p>[1] <a href="https://www.ebay.com/itm/Lot-of-3-Vintage-Lena-Liu-Country-Accents-Numbered-Bradford-Exchange-1995-Plates/114738731393" rel="nofollow">https://www.ebay.com/itm/Lot-of-3-Vintage-Lena-Liu-Country-A...</a><p>[2] <a href="https://www.ebay.com/itm/Three-Stooges-Pop-Art-The-Franklin-Mint-Heirloom-Collector-Plate-1994-Rt-0030/313263518547" rel="nofollow">https://www.ebay.com/itm/Three-Stooges-Pop-Art-The-Franklin-...</a>
