If you don’t care about where or when duplicate experiences exist (e.g. their density in the universe), only their number, then not caring about duplicates at all gives you a fanatical wager against the universe having infinitely many moral patients, e.g. by being infinitely large spatially, going on forever in time, having infinitely many pocket universes.
It would also give you a wager against the many-worlds interpretation of quantum mechanics, because there will be copies of you having identical experiences in (at least slightly) already physically distinct branches.
That being said, if you maximize EV over normative uncertainty about this issue, e.g. fix the moral view except for its stance on how to individuate and count duplicates, then the wager against duplicates disappears, and duplicates will count in expectation. You may even get a wager for intuitively massively redundant counting, where the you there now is actually a huge number of separate minds and moral patients, by counting each conscious subset of your brain (e.g. Crummett, 2022).
