This is a reductionist view of even the suburban United States IMO. There are plenty of locales in what I'd call 'middle suburbia', which I'd define as less than an hour from whatever their geographical city center is. Even in these areas, multiple day power outages, or other localized or regional disasters have been endemic in the last 25 years; often due to utility or local resource mismanagement.

Take, for example, the 2018 California Camp Fire, the various southern winter flash power outages, or the endemic hurricane season pretty much everywhere exposed to the middle or southern pacific.

"For hurricanes" is a cute way to minimize it, but in much of the country it's rather little that separates you from being left to your own devices, at least for a little while, even when you're just suburban and haven't even looked out to the rural U.S.

There is a real deferred maintenance and resource mismanagement issue in this country. The increasing evidence of "preppers" and items like ration buckets becoming prevalent at bulk store operations like Walmart & Costco are early indications of the increasing prevalence of these issues.

Take a survey of the items that are always available at most Costos or Sam's Clubs across the country and you'll see similar results. They essentially market decentralized infrastructure for those that can afford it (or those who can't afford not to have it).
