While I find stories of archaeology interesting, and by with pirates doubly-so, Clifford (and his co-author, Perry) did not do a good job of staying on the narrative of the excavation, and instead offer up too many criticisms of people who got in the way, and too many pats to their own backs. One of the groups that Clifford goes to great pains to criticize are the academic archaeologists who disagree with him, and in doing so takes a shit on the whole discipline of archaeology from too great of a height. While some of his complaints about them are true, the fact remains that a given site can only be excavated once. While Clifford may or may not have taken the necessary precautions, if we accepted his argument then it would be that money, not brains or a sense of curatorship, would be the ultimate arbiter of access to a site, ignoring the shared social value of historic sites.
