So if I was your Chief Strategy Officer at mempool, I would recommend you simply set a minimum UTXO set per OP_PUSHDATA. For the book example above, I might demand the author write his book into a UTXO set worth $1.00. That way, mempool not only gets the transaction fee of $1.00, but also can rest easy knowing the author's book must either gain transactions, or the deflationary nature of BitCoin SV would economically incentivize him to self-prune the UTXO-set if the book is a dud. That way mempool won't have to hold it forever and burn electricity for nonsense. Or in short, you'd want to dis-allow users and apps from storing lots of data into a 1-satoshi coin. Sure, it's possible, but it might be awful for Node/Miner economics/profitability.
