It’s just a question of what you’re trying to use these numbers for.

Imputed rent for example is one of those things that’s kind of silly on the face of it but makes various comparisons more reasonable. On the other hand it can also imply a great deal of economic activity that isn’t actually happening.

PPP is the same sort of calculation. If rents crash because a great deal of housing was built it can make GDP comparisons kind of meaningless. The country has more tangible wealth, people are better off, yet GDP falls. That’s not what you want the number to represent.
