Sisyphus and his Global Outreach?

In the public presentation at a 21st May workshop on "Barriers to Participation in Archaeology Online", Dan Pett of the British Museum's Portable Antiquities Scheme specifies the current PAS scope and mission:

“[...] the Portable Antiquities Scheme’s(PAS) attempts to engage a worldwide audience with its online and offline offer [...]

So the British public is paying for a Scheme to persuade the whole outside world that artefact hunting and collecting are kosher ways of treating the buried archaeological heritage? How so? Is that really a useful way to spend public money? Especially when it outright refuses to engage in any serious discussion on how true that is and in what circumstances.It seems to me that the PAS is doing a lot of damage by adopting this approach.
