Look, I don't mean to embarass you, but most of what you've posted doesn't make any sense.
You make a statement like "[carbon monoxide] doesn't just pack up and leave anytime soon" without any proof. You probably didn't know this, but toxicity depends on absorption, distribution, and
elimination. Not all chemicals are equal when it comes to elimination; some accumulate for a long time, some are eliminated very quickly. Why would you assume that CO never exits the body?? When I said it binds to hemoglobin, I didn't say it binds permanently. The site that CO binds is the same site that O2 (oxygen) binds -- they compete for the same location. Secondly the purpose of hemoglobin is not to bind O2 forever. It binds in high concentration of oxygen (the lungs) and releases in low concentration (tissue). The entire nature of this means that the binding is reversible (it is NOT covalent binding). A high level of oxygen will displace the carbon monoxide, and vice-versa. That is, the "antidote" to carbon monoxide poisoning is to get fresh air. You will breathe it out.
Cigarette smoke contains
many chemicals that contribute to cancer. It is an error to suggest that CO actually causes all those things.
The toxic effects of CO are pretty much the same as the effects of lack of oxygen - ie. dizziness, weakness, and eventually death. CO also binds to heme in Cytochrome P450, and inhibits it, but I doubt this is as important.
It is ridiculous to think that a small amount of CO in food can accumulate in any kind of meaningful way. IT IS A GAS, IT IS VOLATILE, IT ESCAPES, IT IS DISPLACED BY OXYGEN, IT EVEN TURNS INTO CO2!! AGRH.

Lack of oxygen in our bodies can damage the brain, the heart, the whole body, even if it doesn't kill us. Oxygen makes up 90% of our energy, the mere 10% comes from food and drink.
I think you are confused. Oxygen doesn't give you any energy at all. Energy is obtained from glucose, as well as anything else that can break down into glucose, or its derivative pyruvate. Oxygen only allows your cells to undergo aerobic respiration, which increases the amount of energy that can be produced from one pyruvate by about 10 times. If you are interested in the mechanism: oxygen is the final electron acceptor in the electron transport chain.
"You are what you eat", and I wouldn't like to consider myself monosodium glutamate, diethylaminoethenal, or trisodium nitrilotriacetate. Do those even have a correct pronunciation?
This is not even an argument!! I don't want to consider myself a tomato, maybe I shouldn't eat that? Leave the figure of speech as what it is, a metaphor. Side note: MSG is awesome.
I'm not even going to talk about the ridiculous "big bad organizations like FDA are evil and don't care about people, only money" cliche, which people like to use as argument.
