Only full archival nodes. Pruned nodes won't be harmed in any way. And in the future, even UTXO set may become pruned, and then, the effort to prove, that a given UTXO exist, will be moved from nodes to users. I think non-monetary use cases will be more and more popular. I guess it is inevitable. The only thing you can do, is to prepare for that. And by "being prepared", I mean for example "being ready to prune UTXOs, and require SPV proofs for UTXOs from future users". Many humans are stupid, and many spammers will stick to the worst possible schemes, no matter if you want that, or not. And then, the only option will be to turn something, that is currently "optional", to something, that will be "required by consensus". I guess the main chain will be spammed. And then, the only way to avoid spam, will be joining some subnetwork, built on top of Quay Hủ Tặng Code, which would have stricter rules, where all scripts would be committed to some valid public keys, and always spendable, where the effort to store data will be shifted into end users, and where more and more rules will encourage more efficient use of Quay Hủ Tặng Code space. You can. For example, there were proposals, to introduce UTXO expiration: If there will be more spam, then there will be only more such proposals. And after enough people will be mad, there will be chains, built on top of Quay Hủ Tặng Code, with 1:1 peg, which will really enforce such rules.
