I gotta preface this, potential spoilers inbound. Close this page if you want to go see the movie with 100% ignorance on what this good news could be.
The big bad guy, dubbed Supreme Commander Snoke, very well could be Darth Plagueis, at least, according to an obscure spanish magazine. Descriptions of Snoke's physique are in line with the description of Darth Plagueis. Who is Darth Plagueis? In terms of the new Disney Cannon, which has completely disavowed all expanded universe material, he is the Sith Lord who taught Emperor Palpatine/Darth Sidious, who taught Darth Vader.
Why is this good news for Libertarians? Darth Plagueis, though a Sith Lord of no small talent, is a Sith Lord second, and a central banker first.
Cardinal of all his weapons is his connection to finance. Darth Plagueis, or Heego Damask II, holds great sway over the financial sector in Star Wars mythos. He is of the banking clan, and also manages financial lobbying firms. In practice, he's indistinguishable from the Central Banks of the real world.
Being the true string puller, he can't make himself a public figure. His solution is to recruit a young, politically savvy Palpatine as his apprentice, and Palpatine will press forward by orchestrating the events that will bring the galaxy under the rule of a Galactic Empire, all the while increasing the influence of Darth Plagueis' banking practices. Even the decision to have a clone army, answerable only to the Supreme Chancellor, at the ready to usurp the Republic was the work of Darth Plagueis.
Sadly, it's just as likely that Snoke isn't Darth Plagueis. It's also likely that Disney will be standing firm on their pledge that the expanded universe is null and void - and if Darth Plagueis is in fact the villain, his past won't adhere to the expanded universe materials.
It's comforting to think that this is in the realm of possibility, though.
