Not to mention, the entire medical system does NOT want to prescribe antibiotics - especially cutting edge ones - unnecessarily, in the interest of dragging out the emergence of antibiotic-resistant strains as long as possible. Some pathogen (commonly, though not exclusively, staph) somewhere will eventually mutate into a resistant strain to some particular antibiotic. This is extremely problematic, because it means that the antibiotic becomes essentially ineffective at eradicating that mutation of the pathogen. If this occurs with a cutting edge antibiotic, and the pathogen happens to be a strain that’s resistant to many other antibiotics, you get what’s called a “superbug”; in the worst case, you’re all the way back to “get some rest, stay hydrated, and good luck”.
