Final answer:
Tourist income for Maori tattoo artists is not a cost but a potential benefit of the global interest in Maori tattooing. The costs include the loss of sacred ceremonies, changes in procedures, and loss of exclusivity.
Step-by-step explanation:
For the Maori, the option that is NOT a cost of the commodification and appropriation of Maori tattooing around the globe is 'tourist income for Maori tattoo artists'. This option actually describes a potential benefit rather than a cost, as it suggests an economic advantage that some Maori tattoo artists may gain from increased interest and demand for their work from tourists. On the other hand, the loss of sacred ceremonies, changes in procedures, and the loss of tribe, clan, and class exclusivity represent significant cultural costs associated with the commodification of traditional Maori tattooing, or Ta Moko. As the tattooing practice becomes more commercialized, it can lead to devaluation of the cultural significance and the potential erasure of unique cultural identities tied to these traditional tattoos.
