It must be particularly useful if you're trying to work around EASA and the lack of customer service it exemplifies in it's geograpical area of operation.
The reality is that there are several thousand private IR holders in Europe of whom the great majority are FAA ones.
This is a simple consequence of the European regulators' screwing of the private IR, over many years.
I think historically most of these people did it all in the USA. This has always been the smoothest and - for any significant amount of flight training e.g. the IR - the cheapest option. A few have done it all in Europe, with visiting DPEs.
Nobody is actually "working around EASA" in that sense.
