Yes, the only solution to keep the inside from fogging up is to have the AC on.
I know for the FR-S if the AC is off the air coming out of the vents is not cooled or dried even if the temperature knob is set to cold/blue (cold/blue just means not heated). This reduces load on the engine and helps fuel economy.
Some cars run the AC compressor on a low setting all the time, meaning the air is cooled and dried a very small amount even with AC in the off mode. Turning on the AC in these cars runs the AC compressor on full.
In the FR-S, AC off mean the compressor is not running at all. AC on means the compressor is running at full capacity.
