Yes but the maxim presupposes the existence of an injured party, and that's a little different in the context of civil claims (e.g. your example of the large corporation bringing a civil suit against someone) compared to the state bringing criminal charges against a person. There are intentional roadblocks to the state bringing charges, e.g. the separation of powers I mentioned above, that don't really exist on the civil side.
It's good that there are checks, but the core point remains that nimbleness is required for effectiveness. I'm not saying you're wrong, I'm observing that the courts are slow, and that the same logic (slow is good) can indicate that is a good thing, which is why I take issue with general application of the concept without limiting context.
