A large portion of antibiotic resistance comes from patients taking a partial prescription, feeling better, and discontinuing the rest of the pills.
In that situation (the only one at this time), is the majority of resistances are made.
Controlling the supply, especially if you know you have a bacterial disease, can be solved readily.
In fact, on a camping trip, I was bit by 15 ticks. Was bad. When I got back to civilization, I started getting spots all over my body. Surprise, it was rocky mountain spotted fever. But if I could determine the 2 drugs for curing spotted fever and Lyme, I absolutely would have did both. But the shitty gatekeeper (doctor) wouldn't do Lyme course. Again, logically made a lot of sense, especially that Lyme tests are 60% accurate. And, 15 ticks.
