I like really fast lenses so that I can reduce flash output to almost ambient light levels but still have a combination of fast shutter speed (1/125) and low iso (200).
Never understood myself - besides the cool factor (in other words: "my lens is bigger than yours").
Adding to your thoughts that (1) a 35/1.4 is just as "fast" as a 50/1 for hand-holding, and (2) no super fast 50 focuses below 1m.

For Bokeh- hard to beat a Sonnar. I think the Zunow 50/1.1 is a Sonnar derivative, but not sure. The Nikkor 5cm F1.4 is the fastest true Sonnar that I know of. The Bokeh is harsh compared with the J-3 and Zeiss.
I use the Nokton for low-light, and the J-3 or Zeiss Sonnar for Bokeh.
… Today, with the ability of high speed digital, and what you can do in post, I personally consider these lenses silly obsolete relics - especially given their bulk. These are for film purists only.
I think that people get spec drunk. Same reason why people get ridiculously powerful engines in their cars. These had a purpose back in the day - film speed was slower and if you wanted to shoot color, you often put correction filters that cut your speed further.
