As I said earlier, Leonardo Da Vinci followed an intense structured training session. That didn't seem to damage his creativity or individuality...
The question is not whether one person who was of the temperment to excel in that structure was creative. The issue is what our world would look like artistically if that had been the ONLY method of art instruction and exposure throughout history. What happened to artists who simply couldn't thrive in that particular structure?
DaVinci was not the "average student". Presumably, there were 100's, if not 1000's of other students who received exactly the same training as DaVinci that we've never heard of and that produced fairly crappy art. There were students who, like college students today, muddled through metalurgy and chemistry just barely "passing" because it was required and never used it again beyond what every artist did to work with their pigments.
Little Leonardo did not become the great DaVinci because of the training method. He became great because of who he was, the talent he had and how he applied all the things he learned because he was fascinated by a large variety of subjects, scientific as well as artistic. The environment of that type of art school was a perfect fit for him.
Another talented artist might have been turned completely off art by the same structure, especially if the establishment in that structure did not see promise in the artist who wouldn't apply himself to the subjects required, but rather preferred to go in a completely new direction. DaVinci
perfected the painting trends being developed at the time but didn't really push the artistic boundaries into new and radical territory. He was an innovative
scientist, but hardly a trailblazer as a painter.
Clearly though, there are many who would like Tango to be full of DaVinci's and hate the arrival of any artist that
changes the boundaries rather than
perfects within them. So if that's what you want, then a standardized method with a structure like what DaVinci experienced will be great. But if that's the only training then we would not have the variety of tango styles we have. We'd all be listening to only Golden Age and dancing however they danced then... (as though they only danced one way then

)
As I said, there are those that wish that were the case, but I thought they were in the minority here? Personally, I like Tango because it is NOT like ballroom.
