Yes, this is clearly not the 12th century, but the parallels can give a good deal of insight into our present world-system.
I think the most interesting thing about looking at the parallels is how similar the models are between 12th century and present. Yes, we move and communicate a lot faster, and there are a lot more of us, but at the core you can still see the same sorts of organizational units showing up, and the relationships between those organizational units function very similarly. That said, you can see some fundamental shifts in the nature of organizations. Slavery is almost universally shunned, which marks one institution that has shifted radically in social importance. Democracies are consequently very different from their historical predecessors.
There's a lot of interesting stuff here. Your post, on the other hand, is reductive and boring.
