On second thought, Maybe he can. The Rikudou Sennin made the moon by using Chibaku Tensei, so maybe Madara could use that or could bring down an asteroid. Though we don't if Madara is on Rikudou's level yet (I personally think that Hagoromo is stronger than Madara).
I can bet that Hagoromo is casual continet buster as Ten tails host.
It is even supported by manga as Obito stated Hagoromo used his sworld(nunoboko) to create the world. Of course it doesn't make sense as world existed before so Obito most likely meant Hagoromo literally reshaped THE ENTIRE WORLD/GLOBE after HIS BATTLE WITH JUUBI.
It alone can speak of Complete Juubi's volume power.
Juubi Jin Hagoromo could be planet buster using his full power focused at one time.
Juubi Jin Madara should be casual country buster with at max being planet buster as
Juubi Jin Obito was casual multi-city buster while at max country to multi-country buster.
What makes you think madara cannot summon an asteriod the size of the one that devastated earth during dinosour age, or even summon the moon and smash it on earth
i think some are misinterpreting the size of a continent. multi city busting? yes, but it's not even a state buster. continents are huge and even with the juubi missing the full chakra of the kyuubi and 8 tails that added chakra does not equal the rest of the continent. even if it uses all the energy it has at one time it still isn't. but given time could it lay waste to a continent? absolutely, but not in a single shot, sorry.
A town doesn't quite equate to anything similar to the size of a continent. Madara has the hype but not so much as the feats. Only the Sage can be considered a continent buster.
Ten tails second form was casual city buster
Ten tails buffed form could be easily multi-cities buster to at max country buster.
This is the ten tails which lacked almost full Kurama and Gyuuki,
Madara's version:
Ten tails second form could be casual country buster
Ten tails buffed form could be casual multi-country buster or small island/small continent buster
It was Ten tails which still lacked half of Kurama.
Ten tails's original form with ALL Nine tailed beasts could be casual continent buster with possibility of being global life-wiper/planet buster.
Even if it is not enough, Ten tails jin > Ten tails are power is focused so
Ten tails Obito - multi-cities casual buster to country buster at full power
Ten tails Madara - casual country buster to continent buster at full power
Ten tails SOSP - casual moon buster to planet buster at full power.
