Sad that instead of having a discussion about this, my point of view gets downvoted. It's true. Where I live, cash has had more downtime than cards. That is just plain fact.
The problem is that while it may be personally true for you in the country where you live over a short window of time, it's not generally true for the world. Internet outages are more common than demonetizations.
I think it really comes down to what you mean by 'internet outage'. Maybe if you're in a smaller town, the one ISP can have a service outage. Or a large hosting service like aws could have an outage. But those are always going to be limited in scope, both in time and users affected - as far as I know, there has never been a time where the entirety of the internet just went down. On the other hand, demonetizations do happen and they do not have the same limitation of scope - they affect every business and cash using citizen of a country.
