@NamikazeNaruto, NE isn't available for anyone. Only those with huge levels of chakra can even try to manipulate it. Just like only those who made a summoning pact with Kurama can wield Kurama. One of the reasons Kurama hated humans was because he kept being used as a tool. A chakra weapon. Nature Energy and Kurama are both external sources. In fact, Kurama is just big mass of Nature Energy anyways, seeing as he's just a split from the Juubi.

@Killman, I believe Madara set his Izanagi with a Transcription Seal or similar. Meaning, he loaded the technique beforehand, with the necessary chakra (meaning he could regenerate while the seal kept the technique and chakra). It was set to negate his death. Similar to Itachi setting Sasuke's eye to use Amaterasu when it saw Obito's Sharingan; Sasuke was out of chakra. So the chakra needed was given by Itachi.
