Why do older camera lenses have faster F-stops?

It's "only" f2.0 because it's also a macro lens.

You are making a limited comparison.  In the specific case of Olympus, the 50mm prime is a macro lens.  There are very, very few macro primes that are f2.0, so it's actually a very fast lens.   If you look at any other system, there are plenty of f1.4 options and even some f1.2 options.

For the Olympus E mount, there is a Panasonic/Leica 25mm f1.4, which represents the 50mm FOV that your old lenses would have had on film.
