Oh no, it's a fine analogy! I just thought you muddled it a little at the end with the 'no one getting sick' part. It's important that source code be available for the same reason that food preparation not be done behind locked doors with secret ingredients - not so much so that everyone can see for themselves, but so that someone can, and raise the alarm for the rest of us if anything is amiss. The 'getting sick' part actually works too - it's important to be able to review the process precisely because it's not always immediately obvious if something is wrong.
