Q: How and/or to whom do I submit an idea regarding how to evolve the
fundamental structure of the Internet and how our society relates to
it?

You might want to create a blog in which your ideas could be
discussed. There isn't any single person or organization that is in
charge of the Internet. The Internet isn't really one big thing, but
many, many small things. It's like a huge hive of bees without a
queen.

Pinky, queen, 
It isn't just one huge hive, but many  - and some with a queen bee - 
like this one.

One of the drones, Myoarin  ;-)

Perhaps you could submit your idea the the people who run the
backbones of the internet. AOL seems to control some major lines, you
can contact them from their webpage here: http://atdn.net/
