Snowcrash enclaves

I had to laugh a little at the idea of enclaves in Snowcrash. While reading this book I had a job interview with the Kohler Corp in the town of, you guessed it, Kohler. The idea of cooperate enclaves is not new in fact they have existed in a small scale since the 19th century in the form of the company town. Lumber towns and mining towns covered northern Wisconsin and the UP and these towns were the world to the employees. And these towns still exist today such as Kohler, but if we look further at the aspect of control not just ownership we can see where these enclaves may spring from. Just take Redmond WA, Microsoft may not own the town, but can exert a large amount of control over the area. Is it inconceivable that in the future this power could not grow into an enclave of sorts?
