Did you actually read the post? They propose to put it on-chain, and even say

> [O]ur NFT collection could very possibly become the largest on-chain collection ever in the history of Ethereum. Time would only be on our side because as gas becomes more expensive, the window of opportunity to bypass our on-chain NFT collection would fade away.

Remember that this is from the people that believe buying a book gives them the IP rights to the work (should have bought a Harry Potter book). They may not have thought it all the way through.

To give an idea of the storage costs associated, I dug up this old stackexchange-answer about storage costs on Ethereum [0], which estimates that it costs about 76.000 USD / GB stored. Note that this is 5 year old answer, so the price will probably have multiplied like the price of ETH since then.

Edit: Here's [1] a newer, updated price estimate that takes current prices into account : 309.9 Million / GB. LoL!

Oh, no-one here is claiming that their idea makes any financial (or technological) sense, just that their idea is indeed storing it on the blockchain.
