I'm afraid you've got it backwards here.
Batuu (the Hawaiian word for methamphetamines, don't forget) is in a distant galaxy a long, long time ago. This clothing was created and exists tens of thousands of years before humans developed on Earth, much less before humans formed distinct cultures in what is now Southeast Asia and began farming rice.
It's the Southeast Asian rice farmers who are guilty of cultural appropriation, and they should be ashamed of themselves! They should send an apology letter to the Batuuvians, and also consider renaming their airport. Shame on the Asians! Shame!
