Ah yes, the standard argument against consequentialism: X has expected positive consequences, so consequentialism says we should do it. But clearly, if people do X, the world will be a worse place. That's why practicing consequentialism makes the world a worse place, and people shouldn't be consequentialists.

Personally I'll stick with consequentialism and say a few extra words in favor of maintaing the consistency of your abstract arguments and your real expectations.
