Although I think much of what you appropriate from others is impossible to 
argue with, I think the conclusions you go on to draw from it are 
fundamentally unsound and don't actually follow.
There are various ways of working with platinum, and for many photographers 
handcoated paper is not a necessary part of this. These included some of the 
finest photographers who have ever made use of platinum - including Frederick 
Evans who I mentioned earlier. In the heyday of platinum few photographers 
used hand coated paper.
I've handcoated and I've used Palladio. If I was starting to print a new 
edition tomorrow I'd probably hand coat, not because it would be in any way 
superior but because I prefer a heavier weight paper (and it might save a 
little money which is short at present!) I don't even feel a better printmaker 
 if I use platinum rather than silver gelatin - it is simply a matter of 
fitting the materials and process to the vision. 
You can also do it just as badly hand coated or Palladio or any other process 
of course. I end up feeling people who have good vision as printmakers make 
good prints, those who don't make bad ones and the choice of medium becomes 
irrelevant.
