Profits, unreasonable expedience, nor CYA medicine shouldn't be the driving forces. Evidence-based medicine should start with knowing what characteristics or which pathogen it is
before dispensing medication. There's only so many prescriptions of a certain class of antimicrobial that can be written before a pathogen evolves, and then it's ICU DoLR time. And then there's the other side-effects: overprescription of Cefdinir for average strep cases has shown to lead to greater risk of infection by resistant C. diff. Microbiome upsets by killing off healthy GI critters too.
While delaying prescriptions campaigns like US CDC may be holistically helpful to discourage some overprescription abuse, it doesn't address the lack of sufficient rapid, systematic, integrated clinical pathological screening and surveillance.
For maximum human benefit, I think essential medical testing services should have a nationwide option provided at minimal costs for anyone including those without health insurance. Some things shouldn't be completely privatized because of the perverse incentives created, like private equity buying up rural hospitals decimating local care options to favor air ambulance services they also own.
I think we can and must do things better and smarter to reduce individual and aggregate harm.
