Of course it doesn't generally work that way. People use the term "free as in beer" to describe when the author gave you some additional rights over all rights reserved.
Its an analogy invented by the Free software movement to describe the difference between "freeware" vs "bsd/gpl/etc" licensed software. "Free as in beer" does not mean "proprietary/all rights reserved".
After all, the ability to sometimes be able to get beer for free isn't how property law works generally; you can't just walk into any store and demand a free beer - most beer isn't free.
