Because Bob, if we stand side by side and take pictures of an average subject in average conditions, we'll both get an average picture. If I use a 28mm lens and you an 18mm, so will the guy beside us with an iPhone.
Shooting a model in a studio at a fashion workshop, whether we have a Canon 5D Mk IV or a Panasonic m43, we're getting the same shots at f11, 1/125s, ISO100.
There are differences to the cameras, though, here DxO in its flawed way maps out what you get for the extra money:
Pentax K-1 vs Pentax K-3 vs Pentax K-5
So you should be shooting to the advantage of your format … in landscapes, get less blown highlights because of the dynamic range, richness in portraits because of the colour depth, less graininess because of the ISO performance.
To shoot with my DA*55 on my K-1, I had to get in fifty percent closer to get the same composition, and look what that's done for the bokeh:
The wider angles go much wider and more spectacular. Here, the DA12-24 at 16mm on the K-1 had me standing so close I was getting the elongation of the limbs and pushing back of the head and torso that I wanted by perspective distortion:

Sure, Bob, unless you change your shooting style, it's going to be a much of a muchness.
If you point both cameras at your backyard and go click with the same exposure, you may well be disappointed at how similar the pics look on your phone, tablet or even laptop at normal size. The extra pixels get resampled in downsize, for starters.

Nuh, this is the 'total light' fallacy.
Whether it is a full frame or crop sensor, in both cases of your example there are only 45 line pairs per millimetre coming through the lens.
There is no difference in that resolution.
You can say that you get 36/24 more lines, but you *also* get 24/36 fewer pixels to resolve them - you're running on the spot! :)

But there will be 36/24 times less pixels on each line, right? ☺

What? You seem like you want to believe that, Zoolander. 😀

It's a lot of money for something that won't improve most photos we take, or for some people, any photos they take. APS-C is an excellent compromise on the various available formats.
I have the K-1, and an A7 before it, but understand anyone sceptical of whether it will improve their photography. It will improve certain kinds of shots, and all of us have to decide whether the extra money, weight, softer corners and reduced depth of field are worth it. I will still also be using my K-30 as I've always done.
No different from debate about buying an expensive lens, IMHO.
