Unfortunately most local doctors/GPs have this attitude. They have a lot of patients to see and don't want to make life complicated for themselves, so it's simply easier to avoid Vitrectomies unless absolutely necessary.

It is only the odd specialist that is willing to hear your side of the story and carry out an FOV.

If your floaters are due to head trauma than IMO it's less likely you'll develop a full PVD as your vitreous is probably in good health.  I think I read elsewhere that your eyesight is also perfect, which is probably another sign that you've got a healthy vitreous and retina.
 

  
It's more likely the doctor believes the risks outweigh the benefit.  If the surgery doesn't go well you could end up with partial or complete loss of vision, which I would say is worse than floaters.
