The parent post was referring to GPs, which at least in the U.S. aren't often operating in hospitals, and certainly don't get ID consults.
Vancomycin is the drug of choice for several major infections that are of a concern to hospitals (MRSA, C. difficile) because there's already pretty established resistance mechanisms. There are definitely some "more last ditch" drugs, but Vancomycin is kind of the first of the "Now we bring out the big guns" antibiotics.
Partially because it's a PITA to give to patients, and has some toxicity problems.
