Terrence Witkowski on Collectors, the Market and Looting

Artefact dealers and collectors deny the concept of preservationists who proclaim that it is no-questions-asking collectors that are the real looters of the past. They say archaeologists and other preservationists "do not understand the market". So here is an interesting article:

Terrence H. Witkowski, 'Trade Ceramics, the Antiquities Market, and the Preservation of Southeast Asia’s Cultural Heritage'
Abstract:

The buying and selling of antiquities has long been entangled with looting and trafficking activities and, in the process, has done damage to the cultural heritage of source countries.  This paper investigates the market for Southeast Asian antiquities, specifically trade ceramics, the early pottery and porcelain exported throughout the region centuries ago.

I do not anticipate seeing a rebuttal from the antiquities traders' lobbyists or collectors, do you?
