I disagree. Strongly. The (our) most precious resource is time. Our time is finite, and thus constrains agency.
Like money, agency is (to a degree) within our reach. It can come and it can go. Time on the other hand, simply runs out. Time can be be taken, it can be given, and it can be squandered. It can never be returned (overtime today repaid by a vacation tomorrow is still time lost today).
If you're salaried you know exactly how much you're selling your time for. Real wealth is when ALL your time is yours to do with as you please. Agency therefore is simply one means to that end.
Gemalto manufactures and assembles many, many products in Europe. The entire European security cluster won't use anything else. I know because I played a part in smart card development there. And all of that was from Europe. Wafers, chips, holograms, mag stripes...
