PPP-adjusted GDP answers “how much stuff can someone in a country buy at that country's prices".
Just because someone in India pays the equivalent of $1 for medicine that you pay $25 for, doesn't mean their medicine purchase "essentially" caused $25 worth of economic activity to occur. I'm oversimplifying it but people misuse the PPP-adjusted GPD metrics in this manner.
