Price the long Pro lenses against the big 3 equivalents, in those cases where there is an equivalent. For the same field of view the price is about half, the size and weight are not comparable. And compare the Oly 12-100 f/4 Pro againt a big3 equivalent in size, weight, and price.
I was curious about your statement, because I own and love Olympus Micro 4/3 cameras and lenses. I don't own any Nikon cameras or lenses.* It doesn't appear to be true that the price is half for longer lenses (or most lenses, for that matter), and in one case it's very not true. I've found one lens where the price was about half. It's generally fairly comparable. Weights are generally less, but not universally. Sizes are almost universally smaller. Here's a sample, assuming APS-C Z camera body. I believe all the listed Z lenses also work on their full-frame cameras.
Size matters. ;-)

* Actually, I own one old manual focus Nikkor micro lens, adapted to my Sony cameras. No Nikon bodies, though, and no Z lenses. So if I were biased, it would probably be the other way.
