Why people collect fine art
Nobody fully understands why a painting by a person who died three hundred years ago should be worth more than a house. The economic explanation is supply and demand, which is true but incomplete. The psychological explanation involves status and beauty and the desire to own something singular, which is closer. The honest explanation is probably that art collecting is one of the oldest forms of saying something about what you value, and the market has evolved to price that expression with extraordinary precision at the high end and remarkable opacity everywhere else
The collector who lives with a painting for thirty years and knows it the way you know a face is experiencing something qualitatively different from the institution that holds it as an asset. Both are valid forms of collecting. The best collections tend to be built by people who started from the former position and arrived at the latter by accident. The Rubells in Miami
The Saatchis in London. The Brandts and the Pinaults. These are people who started collecting from genuine conviction and ended up with collections that also happened to be extraordinary investments. The connection between those two outcomes is not coincidental.
CollectorGrade take
Buy what you want to live with. The art that stays on the wall for thirty years and still holds your attention is the art worth having. The market tends to validate genuine aesthetic conviction over time, though never reliably or predictably.
