Is Yoram Sheftel an Anarcho-Capitalist?

No. Upsetting everyone might be a “necessary condition”, but it is not a “sufficient condition”. (I’m only kidding! There is no requirement to upset everyone.)

Why do I even need to say this?

Because I recall some old version of Wikipedia quoted him self-identifying this way. Can’t find where.

Although, yes, he is on the economic right.
