Why didn't Madara start his own plan when he was still young?

Question

I've seen the newest episodes of the anime, and I was thinking:

I understand that he didn't have the Rinnegan right after the battle with Hashirama, but still, I can't imagine that his recovery from that battle would be so long. He remained alive, and he was the strongest Uchiha, and one of the strongest shinobi in the world (and now with the cells of Hashirama), so why wait for someone (because Obito got to him by chance) if you can start what you want, when you want? With his Eternal Mangekyo Sharingan, he could have built an organization like the Akatsuki, and played in the shadows, just as Obito did. In this way he could have time to search for a pupil, and at the same time, the organization members would search for the Tailed Beasts, and after defeating them, keep them in a "vegetative state" until Madara awakens his Rinnegan to manipulate the Gedo Statue and collect the Bijuu's before he dies (note that he's able to steal the Gedo Statue's power, so with Tailed Beasts inside it, he could have been much stronger, despite his age).

Then pass the Rinnegan to the pupil-> Rinne Tensei-> resurrected Madara has his youth and force back, plus the Tailed Beasts are already in his possession. (And MAYBE even his pupil would've survived and both of them would possess the Rinnegan)-> straight way to Tsuki no Me plan.

Answer 1

Madara didn't know he was going to awaken the Rinnegan. He knew about the story with the Sage of Six Paths and the Juubi, he also probably knew about the existence of the Eternal Tsukuyomi. But without the Rinnegan, his plan couldn't have succeeded at all (because the Rinnegan is needed for the Gedo Mazo).

Since Madara didn't know he was going to awaken the Rinnegan, or what the requirements were, he couldn't have started his plan.

Sure, in retrospect, if he had known he would awaken the Rinnegan at a later point, starting to collect the Bijuu early might have been a clever move.

Note that even his current plan had flaws in it:

• Obito never planned to resurrect Madara. It was Kabuto who made the fatal mistake of reanimating him (having been tempted by Black Zetsu with Madara's corpse), and thinking he could control him. Obito's plan was to complete the Infinite Tsukuyomi himself, and create a world in which Rin lives.

Answer 2

It was never Madara's plan to begin with. He was manipulated by Black Zetsu.

"Seeing them, Madara announces himself the world's saviour, one who has saved the world from itself by replacing the hells of reality with the heavens of dreams. While he is proselytising, Black Zetsu stabs him in the back. Black Zetsu reveals that it has never served Madara, but rather Kaguya Ōtsutsuki, and that it has manipulated him for decades in order to bring about her revival." --- Quoted from Kaguya Ōtsutsuki Strikes.

Black Zetsu is the person who delayed the plan.
