Why shouldn’t I go buy a lottery ticket with quantum-randomly chosen numbers, and then, if I win, perform 1x10^17 rapid quantum decoherence experiments, therefor creating more me-measure in the lottery winning branch and virtually guaranteeing that any given me-observer-moment will fall within a universe where I won?
You’re thinking according what pragmatist calls the “old version” of MWI. In the modern understanding, it’s not that an universe splits into several when a quantum measurement is performed—more like the ‘universes’ were ‘there’ all along but the differences between them used to be in degrees of freedom you don’t care about (such as the thermal noise in the measurement apparatus).

You-measure is conserved in each branch, I believe. You can’t make more of it, only more fragments of it.
