NFT journey on Ethereum began (Yr 2015) much early than the birth of Cryptopunks. It was not until late 2017 when awareness about NFT started with the launch of Cryptokitties that made the public excited.

Since then the NFT use cases have extended from collectibles to tokenization of real-world assets. https://medium.com/coinmonks/current-nft-projects-market-movement-key-stats-dcf0fe33300c
