No. Why are you talking in absolutes after spending so much time on the internet? There are always exceptions.
Muscular body requires a ton of energy and protein to maintain. Not trying to get on a soapbox here, but I am personally trying to minimize my impact on the environment. This includes eating the minimum amount of protein required to stay healthy. I definitely won't waste the additional energy to maintain useless muscles (which are absolutely useless for a desk job), which will not even be visible under the baggy shirts I prefer to wear.
