Too much CO2 isn't too good for you, either. If you get a build-up of CO2 in your blood, the CO2 equilibrates with carbonic acid, lowering your blood's pH. This has all kinds of nasty effects. Our bodies like to live with a pH of about 7.35. Get below 7 and you won't last very long.

This used to be the case, but not anymore. Hospitals were (and still are) a breeding ground for resistant bacteria, MRSA included. These MRSA bacteria caused invasive infections (like pneumonia and bacteremia) that were very hard to treat and lead to many patient deaths. CA-MRSA (community-acquired MRSA) is a relatively new development over the last 10 years or so, and as the name implies, are typically contracted in the community. These bacteria are thankfully less invasive, but tend to cause a lot of skin infections and abscesses. In the ER where I work, I see 3-4 patients every shift with these infections, most who have had no recent exposure to a hospital.

Actually, about 30% of people develop a contact dermatitis due to neomycin, one of the three antimicrobials in triple antibiotic ointment.

You wouldn't want to eat those shrooms, most amanita are deadly.

Because "society" is going to pay for it one way or the other. Would you rather have "high-functioning" children on the autistic spectrum that grow to become productive members of society, or for these same children to flounder without society meeting their needs early in life. It has been shown that early intervention can have a huge impact upon the final outcome of these kids. (IAAP - I am a pediatrician, and I know first hand) So yes, you will pay for it. Would you rather pay a little up front, or pay a lot later on caring for autistic adults that cannot take care of themselves? Or would you like to ignore them, and increase the number of homeless with mental health issues because they cannot fit into society? Your choice.

Nah, my autistic son would tolerate a plastic bracelet just fine. He'd forget it was there in about 5 minutes. ASD is such a broad spectrum of disease, you'd probably get about the same tolerance of a tracking bracelets as in neurotypical toddlers.
