Interesting theory but I noticed a couple of things:
1) The blocks he "rolled" along the wooden platform were perfectly square, the stones at Stonehenge are not.
2) In order to pivot his blocks he placed them on a concrete pad. I suppose you could place a stone slab underneath them, but is that really worth the effort?
I noticed the concrete also, but then I thought "Maybe it's possible to use wooden rollers on thick planks provided the ground were firm enough?"
With the corrugated platform he rolled the stones along, perhaps deeper corrugations would help if the stone was of rectangular cross-section? (Also more hands to push/pull the stone over).
