What are pros and cons around banning castling? Vladimir Kramnik has proposed on chess.com that castling be banned for the good of the game.

What are the kinds of objective points that might be made for &amp; against this idea? Based on these, do you think that Kramnik's idea can succeed?

I am keen to avoid this becoming merely opinion-based. But it's such an interesting idea that it must be worth discussing. I do have a perspective, but am keen to hear others' ideas first.
It would certainly allow for more attacks due to kings being stuck in the center, but fundamentally changing the game, which in a way dumbs it down, is not good. It would be less complex. 

I also do not want to think that I spent 40 years of my life studying something only to have it changed. I do not want the rug pulled out from under me like that.
