Edit: missed the meaning of "blind".
Individual speakers draw crowds, yes. But conferences are also a way for people to share their ideas and establish their names in the first place. A conference that optimizes for crowd draw is enforcing a preexisting hierarchy to the detriment of the community.
A solution is to use the keynote address and invited speakers to draw crowds, while taking blind proposals for most of the actual content.
"What is the goal of X?" is a good question to ask in any social endeavor.

Ok, but nothing's solved, just pushed up a level.
Will it mean those people have equitable chances to do keynotes today - no more so than the current systems.
Will it mean they have a chance to build a professional reputation that may result in invitations to do keynotes tomorrow - yes. This is a good long term win.
Noone cares that your computer graphics made a billion dollars, people care that they are cool.
SIGGRAPH also had, last I checked, the best gender balance of any tech community. One year our Wiki was vandalized claiming that the Archdiocese of Los Angeles was canceling a reception we were having on their property because the organization was supportive of the LGBT community and had strong LGBT membership.
So, yeah, Linus freakin' Torvalds can get rejected once in a while. I think his ego would survive. ;)
