It is worth remembering that law professors have a vested interest in making sure the system work as you described. If contract law was straightforward, they'd be out of job.
That's an admirable goal but if there are any "bugs" in the contract you probably don't want it executed mindlessly. Human language isn't code and even code isn't always perfect so I'd rather not be legally required to throw someone out a window because someone couldn't spell "defederate".
I agreed in the abstract, but not in the specific (the specific professor was one of integrity, and sufficiently famous this was not an issue).
However, it's worth noting the universe is a cesspool of corruption. If you pretend it works the way it ought to and not the way it does, you won't have a very good time or be very successful. The entire legal system is f-ed, and if you pretend it's anything else, you'll end up in prison or worse.
