You think ATM's work all of the time? You think if there is a mass disaster or large unexpected event that ATM's will have enough cash in them to supply the masses with cash? How about a weather even that causes power outages or shuts down credit card terminals and ATM's? I agree that having no cash works beautifully 999/1000 days--but you should always have a little bit on you for those rare occurrences when you actually need it. Unexpected events arise all of the time and fully depending on systems that you have no control over to function perfectly is risky. That's just my 2 cents.
Big believer that everyone should have a three layer type emergency kit plan.
A kit for the car/vehicle. A kit designed as a bug out bag/gear bag. And a smaller belt kit. Each kit, IMHO, should have cash in it.
I particularly feel women should have some cash on them. For example, if they aren't feeling safe in some environment, walk into a storefront and buy something, even something small, and say you don't feel safe, someone is outside, etc, and you will be treated different. Customer versus not customer. People don't think that makes a difference but it does make a difference.
Sometimes you are in a situation where you are getting a lift from someone for something and you want to give them a little gas money. It's handy to have on hand for kids. For example, if you have friends with children, give the kids a little cash if you visit, kids like having a little pocket money for little things that kids like to collect.
If you go somewhere where they do take electronic or credit cards but the entire vibe is off or shady, I'd rather pay cash. I don't need more people knowing more about me.
Depending on your business and work environment, you might naturally carry more cash. I had a half stake in a restaurant for about two years and I carried more cash then and used more cash at the point probably compared to the rest of my entire life combined.
As a business owner, sometimes I need someone to do something for me and it's easier to have cash on hand to give them to say go take care of it.
I come from a different generational timeline. Cash was mostly the only option in many cases. The trick is to have a cash reserve on you different and separate from your "walking around money"
I would consider not having emergency kits built and available to be irresponsible for anyone who has children. And cash inside of them is a practical requirement. In just about every major scale disaster in the modern era, you'll have fathers going out risking major harm in complex dangerous environments to go get baby formula. It's not something many people realize. If something bad happens like a major earthquake or tsunami or something of that nature, and the regular access to normal food stocks is gone, your baby still needs to eat.
Personally I don't get it. Lots of people seem offended about having a used backpack with a tarp in it, some lighters, a full tang knife, some cordage, a stainless steel water bottle, etc, etc. Lots of people here mock that. Everyone laughs until their children are dying.
For people who are single, do what you want.
For people with kids though, you've made a decision to no longer just live your life for yourself.
Our society used to be hunter/gatherer based. Those who didn't plan things out died. And their children died. Even if you planned things out, sometimes you were just really damn unlucky and you died anyway. And your children died for that lack of luck too. This is a society and culture of entitlement and abundance. The assumption is that what you have today will be here tomorrow, and that's just not true.
I'm not going to demand someone else be prepared. But if your kids are starving and and I have to take care of my godson first, sorry, I have other priorities. I wish you luck and hope it works out for you, but that's the deal you made for yourself and your kids.
Should a parent have cash on them for some kind of emergency basis?
I believe any parent should do everything in their power to open up their option tree if something goes bad and they need to adjust to protect their kids.
Most of the time, I meet people in life and I just plain feel sorry for their children. I see entitled selfish smug tone deaf jerks and I envision the kind of example that's being set for those kids. Lots of people are under the impression that someone somewhere or some government is just going to automatically save them.
