The more irrational it is to vote, the stronger the selection bias in the voting population in favour of irrational voters. You might prefer (as I do) that politicians be elected by as rational a population as possible, all else being equal.
(On the other hand, the same bias that reduces voting by more rational people probably also reduces voting by more selfish people, since such benefits as there are from voting typically accrue to the population at large. I’m not sure what level of selfishness I want among the voting population.)
Supposing you were right that it is irrational at the moment to vote, you haven’t shown why we should want to make it rational to do so.

If it means my bayesian altruists are doing something more effective than queuing at the polling station, I’m happy with that.
