The vast majority of new license holders pack it all in within a year or so. It's a really sad state of affairs. There are numerous reasons for this - all discussed here many times in the past - but limiting one's license privileges in such a big way, for the very small saving on the initial effort, is IMHO a bad idea.
Just how many people, as a percentage of active private flyers, use any privileges outside those of the SSEA licence?
As Bern says, not many and if there are a thousand things to think of when going abroad then 1001 is hardly stretching you too far.
It's horses for courses and I fully accept that there are many for whom the PPL is the only reasonable choice but that doesn't mean that there aren't a similar number for whom the NPPL would be just as reasonable.
I fully agree with you, though, that the flight training industry seems to forget about people after the licence issue and then wonder why those people forget about them.
Oh, and tow1709, your instructor is talking bollox.
