Stainless steel is the more convenient option.
Stainless steel is the more convenient option.
People are cooking at home for themselves less and less, and this has its own healthcare cost. Anything that reduces the number of people cooking at home is almost certainly a net loss for public health.
Personally I think each type of material has its place in the kitchen (nonstick, stainless steel, cast iron, enameled cast iron, etc)
You can scrub just fine with a chain scrubber or metal scraper. You shouldn't use Scotch-Brite pads, sandpaper, or other highly abrasive methods, but scrubbing is not an issue.
You shouldn't soak.
You can use most dish soaps. Some detergents are still caustic, but anything you can get on your hands without issue is fine. Don't use Ajax or similar highly alkaline and/or abrasive compounds. No lye.
Re-seasoning after cleaning shouldn't need the oven. Get it hot on medium-low heat, wipe it with a thin layer of a reasonably unsaturated oil (refined olive oil, rapeseed AKA Canola oil, etc.) on a rag. Let it cool. If you really screwed it up repeat the process a once or twice. If you've totally stripped the pan and are putting on a totally new seasoning, 6-10 times is enough.
All that said, I agree about acidic foods. Much like highly alkaline cleaners, they can degrade the seasoning. I use stainless steel for those.
I likewise agree that each type of material has its place. I don't use nonstick because I have pet birds, and even tiny amounts of overheating can cause enough fumes to kill them. The rest are all useful to me.
I've cooked with the same cast iron pan, daily, for years, and it only gave me trouble when I had a habit of soaking it. At some point I stopped doing that, re-seasoned it, and stuck to just soaping, scrubbing, rinsing, and drying. It's never given me problems since. I only had to be careful what I was using it for while I was still re-seasoning it, and I also haven't needed to re-season it since. (I use enough oil just from my normal cooking.)
As far as cooking things like tomato sauce in it, I agree that should be avoided if possible, but the main concern there is damage to the pan, not health. It would take a lot of leaching to get iron poisoning, assuming you don't have hemochromatosis.
