Because those people control a large fraction of the country’s food supply and it would be a disaster if they decided to stop selling it to the rest of us.
In reality, free markets being a thing, this wouldn't happen. We can import from other countries and they need to sell their goods to live.
You’re right that it’s extremely unlikely to get so bad that they get forcibly nationalized. However, my understanding is that market conditions are pretty bad for farmers right now, and have been for years. Any change that makes things worse for them will likely drive some to other lines of work and reduce overall production, driving food prices up.
This particular effect is probably extremely small in practice, but I felt the need to remind HN that not all value is produced in cities.
I'm not so sure it's just the 24/7 life or death coverage that makes that happen though. In solidly red or blue seats the main threat to a senators seat is a challenge from the extreme of their party, left or right, which also pulls them further towards the extremes of their parties.
Population isn't everything. We have states like Alaska, Hawaii and Wyoming which are national treasures with low populations.
Why is cross regional appeal of any value, if these region don't make up even 10% of the combined US population.
If US states were divided by population it would be a different think all together. But California has 40 times as many people as Wyoming.
Cross regional appeal is quoted as an obviously good thing to have, but the core assumption of equal distribution of population has been violated.
