Disproving the SIA disproves the Fine-Tuning Argument and Boltzmann-brain-based arguments

My worst post on LW of all time is Boltzmann brains, like Doomsday, require no explaining . It's currently sitting at -18, which I think would be fair if my argument presented was mistaken. However, no one has of yet has shown me where my argument goes wrong. So, I'm back at it again -- this time with variant examples to use, and gunning after the Fine-Tuning Argument as well as Boltzmann brains. The SIA says that theories of the universe that predict more people we might be should be proportionally more likely. The FTA says that our universe is so unlikely that we need God to explain how we came to be in such an unlikely spot. The idea of Boltzmann brains tries to say that this unlikeliness is vastly even more unlikely, barring some sort of Godlike explanation. Lorenzo Elijah, PhD explains here : A Boltzmann brain is a pocket of low-entropy order that emerges due to quantum fluctuations in an otherwise high-entropy environment. Just imagine what scientists describe as the heat-death of our universe. In that scenario, all the stars and planets have decayed into atoms. The universe is just an ocean of particles without form or structure. Physicists theorise that if this state persis
