The only way the utxo set is less stressed under a bip-110 future is if you assume the advocates are correct and spammers will leave the chain because we have signaled that they are not wanted. They are assuming things will operate in an ideal way. They are fools. All that will happen is that some amount of spam that used to take 1 transaction will take more and each extra transaction is utxo bloat. Spammers will simple use p2sh-wrap or multisig keys to embed data. You turn a utxo efficient system into a fragmented nightmare and accelerate centralizing forces. Gun to my head I’m picking larger a hard drive over having to get all new hardware to up my ram.
