In my view: <\/p>\n<p>1 &#8211; Trust is far more frequently an asymmetric relationship than a symmetric one &#8211; and the retail example is never going to support his argument. A retail shop deliberately exposes itself and its wares to public access (pretty hard to sell stuff if it doesn&#39;t!); it&#39;s in the store&#39;s interest to encourage Kim to say &#8220;I shop at Phil&#39;s!&#8221;. A retail customer has a long-standing (and, if s\/he pays with cash, generally well-founded) expectation of anonymity, and it is not usually in the retail customer&#39;s interest to have their preferences and behaviour disclosed to third parties. <\/p>\n<p>2 &#8211; Trust is very often not only directional (Law 4), but also transitive and subject to &#8216;gradients&#8217;. On the strength of your birth certificate, you can get a passport; you can use that to get an airline ticket; you can use that to get a boarding pass. You can&#39;t use your boarding pass as a substitute for a birth certificate, because at each step in this cycle you have (maybe unwittingly) been sliding downhill in the trust stakes.<\/p>\n<\/blockquote>\n<p dir=ltr>Robin has started <a href=\"http:\/\/blogs.sun.com\/roller\/page\/racingsnake\" class=\"broken_link\">a blog which will have an identity theme<\/a>.
