Well my answer to solipsism is generally along the lines of worlds that have evolved from simpler beginnings will have much higher measure than worlds in which we pop out of the air fully formed (Boltzmann brain like). Evolution requires populations, which implies other observers - real observers - so its not all dreamt. Not sure if that will completely satisfy you though :).
