> Subjective value. Neither an NFT or a trading card provides substantial, measurable utility to its owner. Trading cards kind of do - TCG card prices generally hinge on actual play utility as much as rarity. Outside of really old cards that are just valuable because of their extreme rarity lots of cards that are technically rare are still only worth pennies because they aren't actually any good in the game. While cards that are no rarer or older, but are much better in play are worth tens or hundreds of dollars. And even those cards that are mostly expensive because they're exceptionally old and hard to find, like from first print runs of games that weren't popular yet still differ in price quite heavily based on their utility in actual gameplay. Albeit mostly from the cachet that that gives them rather than from buyers desire to actually play them. e.g. Black Lotus is more valuable than other cards printed in the same quantity in the same set because it's also the most powerful card.
