PPP is only useful for measuring regional purchasing power within a country. As a metric for comparing the relative strength of global economies it is irrelevant.

Just the opposite. PPP is less useful when comparing intra-country than inter-country. It's only relevant because there are barriers to trade, especially in services.

this is economist-brained and about the same as using CPI as the only measure of inflation.

They are models.
