All arguments depend on assumptions ,and yours is no exception.
For one thing , you are assuming fairly strong realism about time. That’s not a feature of all theories, or even all multiversal theories. Tegmarks mathematical multiverse struggles to explain time as a subjective phenomenon.
Actually, I didn’t assume realism about time, but the language we use works this way. Popping into existence may relate to Boltzmann brains which don’t have time.
Prima facie, Boltzman brain theories don’t predict experience. People sometimes try to fix that problem by making additional assumptions about consciousnes, leveraging the fact that no one knows how consciousness works.

Boltzman brains that have some sort of ongoing experience of a stable universe are very problematical ,too.
The could form chains, like in dust theory or its mathematical formalism here: https://arxiv.org/abs/1712.01826
