I found this funny. You can pay with cards, but not with meat. Galle Road
My girlfriend physically took my credit card away. We’re much better off. Digitally, however, I continue to use the card for everything from Amazon books to server costs to music. The digital economy runs almost entirely on credit. There’s almost no concept of cash online. Am I glad I don’t have the credit card in my wallet any more? For sure. Can I live without a credit card at all? Nope. At least not online.
Basically, I don’t use the credit card for real-life purchases anymore. It’s an exclusively digital product – I just use the number to buy stuff online, stuff which I cannot get otherwise.
The entire digital economy runs on credit, with the exception of connecting your bank to PayPal (and emerging mobile payments). And I do buy a lot of stuff online. Psychologically, I’m also a bit better at tracking those purchases. I think. Hence, while I don’t think credit cards are essential for ‘real’ life, they are essential online.
