You're wrong. You don't reflect the Tsukuyomi off of the moon, but you're Mangekyo Sharingan itself is reflected. This allows you to cast a Tsukuyomi that will affect the entire world. Also, the Ten-Tails is an intergral part of the plan. The jutsu wasn't explained enough telling us why. It isn't that you "need a lot of chakra"; you need the Ten-Tails to actually make it work.
