Still, ISTM that inflation just preserves the temperature > distribution which exists when it began,* The idea is before inflation a small volume was able to achieve thermal equilibrium within itself even though the universe was very very young because the volume was so small. But then that small volume started to expand faster than light and exponentially doubled in size at least 100 times every 10^-35 seconds, and today that super tiny volume is our entire observable universe. The FTL expansion is why very distant parts of the CMBR are at almost exactly the same temperature even though today they are not causally connected. And the random quantum variations that must have existed in that very tiny volume before inflation started explains why the temperature of the CMBR is *almost* the same everywhere but not exactly so.
