Because that assures sufficient skills for any situation, an awareness of supply chain providence all the way back to natural dirt, and self-confidence transcending anything life can throw at you.
Even the CDC has discovered "zombie apocalypse preparedness" as a means of ensuring people are trained to handle any situation. Sounds preposterous, yes, but in doing so you know you're ready.
The problem with modern living (now app-based) is that power, data, food, fuel, water, and/or money outages leave too many people quickly desperate. Can you quickly preserve the food in your fridge/freezer without electricity? Can you acquire clean water when the tap runs dry? Do you even know where your food/water comes from, and why that matters? This even extends into sociopolitical policy, regarding how governments redistribute taxes to people who ... wait for it ... are incapable of providing for their basic needs when bad things happen, because they don't know how to provide for basic needs when bad things happen.
It's raining outside right now. Have you ever, in earnest, gathered rainwater for drinking? ever even considered it seriously? How reliant on strangers are you for the most important necessity?

Unless of course it's a modern problem requiring communicating with someone a thousand miles away.
I have no idea how you think a metropolitan centre of millions people, even if all trained in wilderness survival skills, would be able to sustain themselves. They couldn't - there's no way you could feed everyone in a major city by foraging or by killing all the rats or finding wild mushrooms. And I guess you could try to navigate out of city by foot, but you're hoping you're going to be able to outrun the general diaspora.
I still have no idea what apocalypse you're planning for - it's something that you don't have water for, but you do have reliable power, or a generator you'll trust to function after whatever happens. Or you don't plan for any of that, but just assume you can do whatever you need at any time, like a Bear Grylls James Bond.
Understanding how a cell phone works won't help you if you're reduced to stone age tech. Even "iron" would have a hard step to get to with nothing. Stone age man didn't have cell phones not just because they didn't know how to build one, there's layers and layers of society that are relied on in order to work towards modern society.
> And if you understand the complete technology stack, you'll reconsider living in a metropolitan centre.
Only if I assume some survivalist power fantasy fiction will come to pass.
> Can you quickly preserve the food in your fridge/freezer without electricity?
What do you even mean by this?
"The power is out kids! Start a bonfire in the front yard, we're making pemmican and jerky!"
In all seriousness, I've been through a number of multi-day power outages. You leave the door to your fridge/freezer shut as much as possible. When you open it, you make it infrequent and fast. They are well insulated, things stay cold for a long time.
