See dkbrk's comment on this thread. MWI follows naturally from our models of quantum physics. It doesn't make any additional assumptions. It's the simplest possible model that fits the data. It's Copenhagen that makes additional, untestable assumptions. And therefore, by your logic, is unscientific. That is, Copenhagen asserts that the quantum states we don't observe, are destroyed. They have to exist, in some sense, to provide the weird entanglement effects we observe in quantum physics. The whole "the cat is both dead and alive at the same time" thing. MWI just follows naturally from these observations. Copenhagen assumes that there is only one universe, without any justification for this assumption. It assumes that the quantum states we don't observe just cease to exist. It assumes some source of randomness, when "universe splitting" is sufficient to explain observed randomness. It adds a bunch of weirdness that isn't necessary.
