You think of misgendering as someone imposing a false identity on you. This is an injustice because you have a right to determine your own identity.
I view the expectation to utter words I think are false to be the real imposition. I don't think people have total freedom to define themselves however they wish because they are constrained by the necessity to negotiate it with other people. I didn't choose my own gender identity and neither is anyone else entitled to.
I don't think these positions can be reconciled, but I would point out a disadvantage to your approach is that it leaves no possibility to foster peace between people who believe differently. Because if they don't accept your identity they should be written off as hateful.
