You pretty much nailed it. The only real reason for fast lenses nowadays is bokeh isolation. A secondary reason could be for opening up brighter on dSLR's to help see. For any other purpose, you generally get better image quality with a slower lens which has fewer/thinner glass elements inside.

And when you are shooting a moving subject in lower light and are unable to use flash, sports, wedding...please explain how a slow aperture and vr would help and why "they are just for bokeh".

Not the same picture. I would not adjust my aperture based on the amount of light, I'd adjust my ISO or film speed. Adjusting aperture is more like a desperate measure to get something at all, but isn't the same as having a subject entirely in focus. It's kind of the point of the OP is that there is no need to get desperate with opening up beyond what you want to with a modern camera.

The ability to open up and isolate something is a great tool, but it's not for every picture and is not the only reason for a full frame camera.
