Yes I believe that sand substrate can be done with a low risk of impaction. In fact I have raised several clutches of beardies on it with no impaction or death but the one thing this argument for sand is missing is the fact that sand can never be sanitized once it is exposed to feces. So in effect every time your dragon has a bowel movement he is loading the sand with infectious organisms. Regardless of whether you treat for parasites or not your dragon will always have some sort of parasitic load. What you can control is the proliferation of these parasites. In capitivity many animals develop superinfections. This is basically an extremely high parasitic load in fact it is the second or third highest killer of BDs with Fatty liver disease topping the list. They develop these superinfections by constant contact with their feces.
So to my point when using sand you can never completely remove all of the fecal material in the sand regardless of what method you are using to clean or sift your sand. Therefore it is much more likely for your dragon to develop a superinfection on a sand substrate than a shelfliner substrate where it can be spot cleaned by initially removing as much fecal material as possible with a paper towel and then wiping down with a chlorox wipe and then allowed to sit for at least 30 seconds. After that the the spot can be wiped up and diluted with just water, novlasan, or Natures choice disinfectant all of which are BD safe.
This is my most compelling reason for using Shelfliner and being a Microbiologist and doing my own fecals I have definitely noticed a difference in my animals fecals. Again and as Always this is just my opinion from my experiences.

yuck.. I mean the only way you could remove all of it would be to grab that trusty shop vac and do it daily. Or sit there an watch him all day till he poops then quickly scooping it out and surrounding sand. Seems your doing the impossible feat there. "I have exchanged the entire sand before, not because the dragon was sick (the only time he was sick, was right after shipping him to me) but simply because I wanted to". How many times a month do you want to exchange the cage sand completely?
