But to do that would be totally unrealistic.

Not at all. The aircraft is perfectly capable of autolanding in real
life. As far as I know, the actual ground equipment is the same for
all ILS categories. The aircraft equipment differs by category (the
higher the category, the fancier the equipment), but the 737-800 is
fully equipped for Cat IIIc autolanding.

I don't know how often autolanding is used in real life. Apparently
many pilots like to fly the landing and perhaps at least part of the
approach by hand. But they can still autoland if they want to.
