In my personal opinion this is the form support. For example you have your favorite artist and you want to support him or her, and what you do? Of course you give them money by buying their products. Many NFTs like music NFT, for example, are used as event tickets. Many would say that by buying NFTs they own original copy, it’s like when you buy some album from well-known musician or books etc.
Well you are right of course. It’s like buying music album or even videogame. Today, NFT is quite popular and nft artist form proposals on the market and can sell the most expensive NFt in the form, thus making a lot of money. But this is not for nothing, cause artists like for example Beeple or XCOPY have their own unique style which is recognised by many, and thus people want to spend their crypto for their works.
