This is based on a recent piece in the NYT which I cannot now find so apologies both for the repeat and also for the possible garbling of the argument. But art is simply to valuable to be hanging in museums these days. We should sell the lot off and close them all down.

Take, for example, the mythical Vermeer, "Girl who has lost her ears let alone her pearl earring". This is worth, in these days of Russian oligarchs, $100 million. It is also hanging in a public museum in London, owned by some arm of the State.

So, how much does it cost for people to look at this picture? A reasonable discount rate might be 5%. That's what we could get if we flogged the piece and stuck the money into a stock market fund concentrating on yield. Maybe 3% for FTSE as a whole. But with 5% that means that not selling it costs us £5 million a year. Or £13,700 a day, which if museums are open for 10 hours a day means £1,370 an hour. A period of time in which this one picture might have, what, 10 people look at it? Thus, the cost to us of this one picture hanging in a gallery in London is £137 per viewer.

At which point we have to ask whether this is worth it. And we've a method of working that out to. Do we think that we could charge those 10 people an hour £137 each to be able to view the painting? No, clearly and obviously, we do not. Therefore the costs to us as a whole of our possession and display of this painting are less than the benefits that come from our owning and displaying this painting. Having costs higher than benefits is also known as destroying value, something which is properly known as "making us all poorer".

We should therefore sell off all such art and close down the museums.

If those who purchase it then wish to show it to the public all well and good. But they'll be doing that on their dime, not our.
