At worst (smokeless) nicotine is no more harmful than caffeine. In fact nicotine appears to be neuroprotective against Alzheimers, Parkinsons, and general age-related cognitive decline[3].

The most prominent example of chewing tobacco that isn't smoke cured would be Scandinavian-style snus. There's pretty compelling evidence that snus is not associated with oral cancer[1], or at the very least the risk is substantially lower than traditional chewing tobacco.

Here's a better breakdown of carcinogens in cigarette smoke (same book, same author)[0]. The most lethal way tobacco smoking impacts health is through carcinogenic by-products created from metabolizing said tobacco.
"PAH, N-nitrosamines, aromatic amines, 1,3-butadiene, benzene, aldehydes, and ethylene oxide are probably the most important carcinogens because of their carcinogenic potency and levels in cigarette smoke."[0]
To elucidate on one of your points: nicotine isn't on any of the "carcinogens in tobacco" lists, because it, nor any of its metabolites, aren't carcinogens at any dosage that is practically applicable to humans.[1]

Maybe, we're misunderstanding each other. But all those compounds you listed are directly present in smoke itself. I.e. they're not metabolic byproducts.
In fact they're not even related to tobacco specifically. (With the major exception of N-nitrosamine). Cannabis smoke (gram for gram) contains equivalent of higher levels of PAH, benzene, 1,3-butadiene, aldehyde, and aromatic amines.[1] These are all pretty much universal byproducts of burning any type of dried plant material, and the same reason that exposures are similar for wood-burning fireplaces.[2]

watching anyone die is hard. no matter what we do, it will probably have a factor in our death.
The argument that anything can be bad so therefore nothing is bad is a meaningless slippery slope. Clearly there are differences and you have to draw the line somewhere.
What's the rationale for drawing the line at a particular substance?
There are known things we can do to substantially reduce harm to the public. It’s always a balancing act between a “parental gov” and individual liberty: there is no universal answer. But over time we learn as humans what we think those trade offs should be.
Note I’m not necessarily for making sins illegal personally, but I am for finding ways to regulate the hell out of them.
IMO the middle ground is to restrict the marketing, not the sale.
Not that I think we should, but we do. Grocery stores like Whole Foods have entire aisles dedicated to snake-oil.
For the first two, we definitely do. No one says you can't let your meat rot before you eat it, and certain forms of rotten food are cultural delicacies. Most groceries have aisles full of ineffective junk medicine. Not wearing seatbelts I will grant you, although enforcement of those laws is generally very lax in my experience.
I strongly disagree with regulating them. Consumers should be given information to make a well informed decision, and then we should butt out. You don't want to wear a seat belt? It increases your risk of dying as a result of a crash by XX%. Go for it if you are willing to take that risk.
I don't feel right imposing my own personal values on someone else when their actions aren't harming others (which I know is somewhat debatable with seatbelts). Nothing makes me feel that my own values and morals are superior enough to force them on someone else.
For example, while we can attempt to justify our reaction to weed by the harms it does, in light of the harms alcohol does and the treatment it gets, one wouldn't be wrong to wonder if our treatment of weed was tied to some other factor that we aren't willing to admit.
Vice industries often point to each other when trying to justify themselves, which I suppose demonstrates that there is safety in numbers. The strategy of tackling one problem at a time is countered by demands for all-or-nothing tactics, with "all" being obviously and conveniently impractical.
If it's the former, I'm with you.
