Most people (by pure numbers) by definition live in very large cities. In fact, in the USA, most Americans live in very large coastal cities. So that argument doesn't hold water.
When the "urban/rural" divide is brought up in American political discourse, it's always done so describing extremes. Yet living in a city - even a large city, doesn't always mean living in an urban "pressure cooker," nor does living outside of a city mean seeing more wildlife than people. I live in a suburb of Austin. I don't hunt my own food or drink from a well, nor am I surrounded by concrete jungle.
The premise that urban and rural dwellers generally have such radically divergent ways of life that it's infeasible for a single entity to govern both is a bit of a populist myth.
'A suburb of Austin' may not be rural by many definitions. Its another city? Look at a map. See all those spaces between a city and its suburbs, and the next city and its suburbs? That's where 'rural' is.
I can see half a mile in any direction, and not see another human habitation. Clearly this is rural. And clearly, things around here work a little differently from a city. For instance, I pay for fire service (volunteer fire association; I donate). I essentially don't have police service except for cleaning up after major catastrophes (half a dozen sheriffs per 100 square miles). I saw an eagle swoop by my kitchen window the other night, with a rabbit in its claws (yeah eagle! I'm a gardener). When the deer get out of hand harvesting my garden before I do, I'm allowed to shoot them. With one of my guns, a bigger one because the little ones are for varmints like rabbit, skunk, rats, the occasional badger.
My interactions with a neighbor are purely voluntary, because other than annual discussions about fences (and the fireman's ball) we have little we need to talk about. There are no association rules; there are no inspections nor even inspectors. If my neighbor parks a bunch of trailers behind his windbreak in an ugly rusting mess, go neighbor. I guess I'll just plant a row of trees and wait 10 years to mask the view in that direction.

Except no one who talks about "city dwellers" is talking about people living in small towns or suburbs. And if I am living in a city, it doesn't conform to any of the political or cultural assumptions that the urban/rural divide makes about "city dwellers." It also isn't nearly as rural as your definition of "rural," although I've lived in those areas as well. I certainly don't think it would be accurate to lump the culture and community of the town I'm in with LA or New York - certainly people there would consider me rural.
And maybe that's one problem - "city dweller" and "rural" are vague and subjective labels.
>So just call me Mr. Populist Myth I guess.
The myth is that your experience is typical for Americans not living in large cities. It's an outlier, not the norm.
>their concerns are not addressed by rules made up in the Capitol City
They are, depending on the concern. Rural voters have representatives and lobbyists in Washington and there are plenty of laws intended to favor rural interests. Part of the argument in this thread is that the Electoral College itself gives rural states out-sized influence in determining the Presidency. It isn't true that Washington is ignoring rural populations entirely, or that they have no political power.
Most of the issues you listed upthread as examples of how urban and rural lives differ are examples of issues which should be (and usually are) handled locally, not nationally. Gun control might be an exception (although personally I believe it should be entirely a state issue) but I think it would be absurd to claim that rural populations don't have a powerful influence on that through the NRA already, given that most of the country supports stricter gun control laws than would ever be politically feasible in the US.
Locally being a euphemism for "by folks in the State capitol"?
Sure there are attempts to design government to balance rural and urban. They work better or worse, at each level. Abolishing them because they are 'out of balance' is maybe not the best solution.
