Still think they should allow NVFR. At least allow pilots to get home same day. If they are really worried about it limit it up to say 90 to 120 minutes. No one is suggesting you fly NVFR 5 hours across the Simpson Desert or other remote regions.
There is nothing dangerous about NVFR if the pilot is rated for it and current. Currency is everything in any operation be it IFR, twins, etc.
Would the CASA people only travel by train after dark because driving at night is too dangerous? Didn't think so.
