Lorde admits the satire used in both the lyrics and music video. Basically the song/album is poking fun at white girls obsessed with crystals, supplements and self healing. The same type who wants to "fly somewhere East" to find themselves, Eat Pray Love style(aka leeching off other cultures without giving a f*ck about the natives).
Also the bad wig she's wearing in the music video was intentional she says and meant to set herself apart from the character she's playing.
Nature is healing, essential oils for everyone!
