its naive to think that.
Of course its been made beautified, and these so-called therapeutic function really has a hidden purpose - to heal during the war, even in the battlefield, to rip off gullible public since i know hardly any of those 'civil use' of martial arts therapeutic uses ever works. People get lured in these so call magical healing powers and mythical benefits is really accounted from people's own will power to heal themselve doing such exercises. I bet you none of these will cure cancer, not cure depression.
the dancing bit has alot to do with 'celebration' as a kind of 'we are the best' "we can hurt others at will' 'the triumph of the adversary in a way to reaffirm them believe their own styles of fighting is the treasure - some culture wil go as far as attaching its magical gifts from certain animals, even worship the animal (s)! the chinese are particularly famous for that. the dragon dancing isnt just what they do in streets to make beautiful festive movements/display in a celebration. It is also part of the shaolin kung fu (hardwork) significance. Dragon is one 'such animal' that kung fu has based itself on, pray mantis, snake,crane (bird), bear, monkey and so on and on
Taichi looks beautiful (it can be) but it is also a slow form of deadly movements mimicking certain animal behaviour -again chinese studied animals movements and incorporated into their own 'culture'
the major for exercise LOL, something like that, it is also had to be 'beautiful' in order to sell, no wonder we have many rich asians in the west they held classes just for that, not impressive. its fraud in my opinion
