&gt; iPhone production can increase as much as demand asks for. If we let anybody build one, there&#x27;ll easily be an iPhone for everybody that wants one.<p>What? This statement makes no sense. Here, let me demonstrate by quoting an ancient islander who likes to build statues:<p>&gt; Tree production can increase as much as demand asks for. If we let anybody grow one, there&#x27;ll easily be a Tree for everybody that wants to cut one down.<p>It&#x27;s absurd! and exactly the thinking that will lead to people cutting down the last tree. iPhones depend on resources just as much as those trees, if not more.
