Whether they're new / old or well / poorly serviced is just a difference of a few decades.
If there isn't money to service old lines now, then there won't be money to service formerly-new lines in 30 years.
Kinda crazy to see the entire I-5 length between San Francisco and Los Angeles classified as "metro". Perhaps the metric they're using doesn't work so well when counties (which is what they classify) are so large, and they primarily care that some city of over 50k people exists in it "somewhere". Some of those counties appear to be as large as or larger than some of the smaller states in the Northeast.
As you suggest, a lot of what is classified as urban is not urban especially by the standards of someone who barely considers the South Bay as urban.
Certainly I can normally go into town for an evening of theater but most people would consider my house to be in an urban setting.

I guess you can argue that a large closely held company isn't a family farm, but it isn't what "corporate" is meant to conjure up either.
That’s why the overall number of farms and farmers has gone down - the little guy can’t make it work economically.
People complaining about corporate farming are talking about outside money coming in and taking the land.
The supermajority of people working American farms and meat shops are Latino immigrants.
Sure the coasts are creating more economic output by far, but people need to eat food. Agriculture is always going to be important, but lot less people are involved in it than ever before. This is part of what's led to the urban/rural divide where the rural folks feel left out - there just aren't as many of them as populations have migrated to cities. This is why people in rural areas feel increasingly left out. It's mostly due to economic forces that are out of their control.
