Why taijutsu is effective against madara
If you know a bit about the ninja history, you can see that the ninja's then used 5 elements!
earth(do), water(sui), fire(ka), wood(moku) and metal (kin), each of these elements cite to a group of techniques.
Do cited to things like running on a vertical wall, sui were projectile techniques, ka was used for the concentration techniques, moku was taijutsu, kin were the weapontechniques( swords etc..).
Now you can see why masashi kishimoto thought that taijutsu had to be effective against madara because the first used wood-style against him that was very effective.
