Three points:
(i) The criterion "that matter" is a function of the use made of the
evidence. When we are interested in the availability of goods and
services, their being produced in the non-market sector is not
necessarily relevant.
(ii) If paid workers work more and, thus, produce more, there is no
need for any inflationary pressure as long as they do not try,
ceteris paribus, to purchase more than their additional contribution
to output.
(iii) As the writing of economic history teaches us, market-based
estimates of standards of living are unreliable when much of
production is home-consumed, communally allocated without charge, or
merely appropriated by extortion (military or criminal). All three
were dominant for all but the last few centuries.
Until recently, a great portion of home consumption on the Israeli
kibbutz was provided according to need and without charge. I recall
discussing with an Israeli economist a few years ago the problem of
GDP calculation in those old days and the procedural adjustment to
be made in the modern era when market exchange has become quite
common within such communities.
