Sure, but that's not a remotely accurate description of a house without a backup battery or generator.
I grew up in hurricane country and weathered many bad storms. Losing power does not put you immediately in an emergency. If you don't open the fridge much, your perishables will last a couple of days. Non-perishables will last much longer. Having a battery is the difference between "we can hang out and grill dinner for 5 days before we need to hit the road" and "we can hang out and grill dinner for 6 days before we need to hit the road". That distinction does not significantly change your strategy.
Losing water is a much bigger emergency but is thankfully rarer and a backup battery won't help.
Climate change will change this story somewhat in the South. If you are in a very hot climate, elderly, or have other health issues, then losing electricity and air conditioning in the summer can be an immediate emergency. Again, though, A/Cs consume so much electricity that a backup battery won't help you much.
I think you're significantly overestimating the emergency value of a battery backup. Loss of electricity is rarely a rapid emergency. In cases where it is, a generator will at least give you as much power as you care to store fuel.
Winter is a better use case, because losing power during deep sub-zero temps can lead to plumbing damage and even be dangerous, but doesn't require too much power if heat uses natural gas as the main power source.
Generators don’t work that well. They need regular use and maintenance. Fuel storage is complicated (you will need 30+ gallons a day, or about 2 sedan tank’s worth. Connecting to your panel is expensive at least $2k+. They are smelly and noisy. And if it’s a real emergency, everyone will know you have one , and eventually come knocking.
For $2k you can buy 3 Ankers and distribute around the house. With a propane camp stove you can cook. So the only utility failing during a power outage is your air conn. If it’s winter you can run a gas fireplace to keep warm.
In my area we have power outages in the fall and winter wind storms due to trees falling. We need electricity for the fridge, fireplace, lighting , internet & devices. Lithium batteries work great. We get a few outages every season, usually for 2-6 hours .
My neighbors have a generator for “emergencies” and don’t end up using it because it’s such a PITA. He has it for SHTF, but then he will have to consume the gas from his cars (and siphon it), which means making the decision between home comfort and evac.
My point is that every solution covers a range of scenarios based on convenience, cost, resilience, versatility and more. There is no one size fits all .
And now these lithium battery backups provide a broad amount of coverage that is safe and convenient for novices to run.

I don't mean it as one. Resiliency is my end goal, and "a reasonable amount" at that, not "I can reboot civilization from the zombie hordes with just what is in my shed". If you are already resilient with just a house and what it will naturally do without power, hey, great. A battery opens up options, but if it is not worth it, it isn't worth it.
It should be a social expectation that you can survive a reasonable 2-3 days without power and whatever other service outage you have without having to immediately hit the stores or drawing on emergency services. I do not care exactly how you achieve that. I don't care if you're carrying on like nothing happened in a well-lit house with AC on full blast or if you're eating beans out of a can and drinking bottled water. I just care that people should be expected to be at least a little resilient, for all sorts of pro-social reasons, that if you have your additional needs like an oxygen machine or necessary medicine that you have the buffer in place, and so on. (Which does imply certain perscription practices keeping you on a short leash are in violation of this, but that's another discussion.)
