I don't think this is a good argument against SIA. The most natural interpretation of SIA gives a posterior of zero for each Ti, so it doesn't actually say we "live in the universe with the most people".
"T{i+1} is half a trillion times as likely as Ti" doesn't actually imply "T{i+1} is more likely than Ti", because those probabilities are both zero.
