Digital Vs film photography and post-processing

[Marko]

My question is can we produce pictures of acceptable quality that need not be retouched from a digital camera? If so, does it mean expensive gears or more expertise?

For me the key word here is retouched....and unless I'm off I think you made a mistake with that word. I think you meant to say-post processed (which includes all the work done to a photo before it's published or printed).
and if indeed you meant to say post processed - the answer is NO.
However the answer is NO with film cameras as well.

All good images that are better than snapshots will need some dodging (lightening a specific part) and burning (darkening a specific part) - period. All the camera does is take an average of the tones in a scene and feed you back an image with those averaged out tones. Usually the result is good BUT IT IS ONLY THE STARTING POINT. Then you as the artist with real eyes will have to make the decision - this zone is too dark and you'll fix it or this zone is too light and you'll fix it. You will ALWAYS have to do this. Always.

Unless I'm off again, I am reading into the fact that you are frustrated with this process somewhat....but it was the same process in a traditional darkroom - and it will never change in my opinion. As you get better at looking at an image and 'seeing' what needs to be done, your frustration will diminish.

Remember even though they say a monkey can take a picture, it will almost always be a bad picture. Great photography is hard work.

Hope that helps,
