It&#x27;s unclear if you&#x27;re trolling, but assuming you&#x27;re not, the analogy doesn&#x27;t work because digital things and physical things behave in fundamentally different ways.<p>In the physical example, according to the FBI&#x27;s &quot;just this one iPhone&quot; claim, one would reasonably expect that the company could then destroy the hypothetical master key as soon as it&#x27;s used.  This makes sense in a physical world, but the analogy breaks down completely in a digital world.  [Returning your spider doesn&#x27;t solve the problem](<a href="http:&#x2F;&#x2F;www.27bslash6.com&#x2F;overdue.html" rel="nofollow">http:&#x2F;&#x2F;www.27bslash6.com&#x2F;overdue.html</a>).<p>In the digital world, you can&#x27;t guarantee that the key hasn&#x27;t been copied, and you can&#x27;t guarantee that destroying the &quot;original instance&quot; of the key destroys all others.<p>The custom OS that the FBI is asking Apple to build will also take development time, and likely take more than one person to develop, meaning that if there&#x27;s a security breach during the OS&#x27;s development, any number of intermediate builds may also be stolen <i>during development</i>, before the FBI can even access the particular phone in question.
