I had a period, 5-7 years ago where I was paying as much as possible with cash and it was awesome. At the time I was single and earning enough not to count my money. I made the mistake to spend a bit too much and didn't save as much as I could/should (e.g. didn't bought enough cheap sats). Now I have to split my earning and we must track our expense and follow a buget. It's almost impossible if we pay too much cash, so card help to have a list of purchases easy to export to a spreadsheet. Also I have card with some cashback that help to save a little extra.

But I really wish I could earn enough more to not care again about budget and tracking expenses. I hate to know that I'm tracked as easily as I do by my banks, card company and even Google (for the rare cases I need to pay with phone).

At least in my country it's still very common to pay cash, 99% of the time it's accepted and even sometimes it's cash only (barbershop, small restaurant, food trucks, itinary fair attractions, ...)
