I think salient points are made by both sides in this exchange, it doesn't seem naive to me to take a view which incorporates elements of each argument.

I like this comment from Burl :

"As I have said, there is no argument between us about the existence of ancient lines and rows. For example, there are the three standing stones in line with a fourth in the recumbent stone circle of Castle Fraser in Aberdeenshire about which we have corresponded. This however, does not amount to a ley in the classical Watkins’ sense. Even if such sites are acknowledged to be deliberately aligned it is a long jump from there to the network of long straight tracks which Watkins’ imagination spread over the landscape."
