This is a claim that you have yet to back up with anything beyond general hand-waving. Much like Fermat, the time I care to devote to correcting people who are wrong on the internet is too small to contain the full argument which would go beyond hand waving. Here's a bit more hand waving: Immune systems are complex and dynamic system designed to deal with unknown and novel agents. That's why simply coming up with something new, is not nearly enough. 99.99% of new mutations are deleterious. And the 0.001% that might be something? Like I said, just one more bullet in a machine gun shootout. Dumping things down the drain does not make bacteria pick them up. You can dump MRSA down the drain all day long, it won't make the bacteria in there antibiotic resistant. Because there is no free lunch, even beneficial mutations are metabolically expensive, and that's why if you dump MRSA in the sewer, over time even they would lose their own antibiotic resistance. Without antibiotics they would be out competed by Staph. which doesn't waste resources on antibiotic resistance. The difference between hacking code and hacking biology is that with code one single bit can cause the whole system to crash or behave in wildly unpredictable ways. Biology on the other hand is extremely robust. Suffice it to say we agree to disagree.
