An outcome you do not prefer is not automatically irrational. You just don't prefer it. The solution is not to wish everyone would act against their own interests to produce your preferred outcome, but to change the incentives so that your preferred outcome is the natural result of rational choices.
It has nothing to do with my preference. An outcome that fails to result in anyone voting for a system intended to get people to vote, is a failed outcome, no matter how you look at it.
