Same applies to physical goods though. For example a big mac has a different price around the world based on the average purchasing power of the region.

This has to do with the labour costs, too, though. Poorer countries have lower purchasing power, but also lower labour costs, reducing the cost it takes to produce a Big Mac.

That's a valid point. Also explains why an iPhone still costs the same since its not locally built.

Also because it is trivial to buy an iPhone in a poorer country and bring it to a richer one.
