I absolutely agree with you and I think most people that are against BIP-110 do as well. In spirit, it would be ideal if there were no monkey jpegs on #Bitcoin.
One of the areas where the BIP-110 argument fails for me is that it assumes that everything will work correctly and there will be no unintended consequences of their soft fork despite a tiny developer team. Making changes to Bitcoin is always a risk. To me, the risk/reward calculation is not there to justify this change. It has been demonstrated several times that spammers will run out of money. Today (and for months prior) I can send transactions for next to nothing.
I also think this change succeeding would set a terrible precidend that would be exploited by governments. Two crazy guys and a loud minority of social media keyboard warriors shouldn't be able to change Bitcoin. If they can, I will probably exit Bitcoin entirely as that would demonstrate to me that Bitcoin could easily be destroyed by a motivated attacker.
