This is very interesting, but I'd like to see some discussion of just what a collection is and what makes someone a collector.

Suppose I logged into that Amazing Prime online retail store and bought a Ferrari Testarrosa, $345,678 including tax, tag, and title. Free 2-day delivery. Would that make me a car collector? I mean, I now own one of the most amazing vehicles on the planet.

I would think not. You have only one, and one does not constitute a collection. Or you could go hog-wild and slap down the Amex Black and buy dozens of sports cars and still not really be a collector; just someone with a bunch of expensive junk cluttering up the place. Collections need themes, motifs, purposes, and some organized mechanism for display and presentation. A little exploration of what the word 'curated' means might be appropriate.
