Even if the electricity source would burn similar fuel, just the fact that you don't pullote right in the middle of population centers makes a huge difference. In reality, it's not only that, but _also_ that they use cleaner methods of energy production.
Huh, no. Pollution close to humans is bad for both city and rural people.

"The solution to pollution is dilution". We want the concentration of pollution low, so the health effects are low too, and we can give natural processes the time to decay/oxidize/etc the pollutants.

We do... we mostly care about the lower ~100 meters of atmosphere because that's where people live. That's less than 1% of the total atmosphere. This means we can distribute pollution over a volume a 100x larger than that that is important for us. And then I'm not even counting the vast amount of the planet that's uninhabited / non-land.
Also, smokestacks are designed to not directly pollute the air close to people, see:
