Resilience. Put on your systems theory hat when thinking about alternatives. FWIW, As was discussed in the post, ground/departure channels at a major airport were overwhelmingly busy for a private pilot untrained in that environment. As an occasional private passenger, I'm accustomed to quite low radio traffic because of the routes and airports we use. I've heard radio so quiet that a Controller handed us off to... herself on a different frequency for a different airspace.
