I have to agree 100% with the Dr.
That is like saying a LOC is dangerous Vs an ILS. no it is not, it is just different and if flown as published is safe.
The FACT is with a LPV WAAS approach, there will be far more effective landings from approaches in crap weather. Safety may not be different if flown by the book. but the results as far as landings will improve.
The biggest benefit is for not just folk like me, who would be better off having lower minima, by just getting in, but for the RFDS, regional airlines and other corporate folk who waste millions of dollars in jet fuel doing several approaches or diverting all for the sake of 300 feet.
WAAS is in my opinion more important than some stupid NBN.....we want aircraft landing in the bush and regional centres....not faster porn!
The sooner the pollies get this fact the better.
