So, electronic payments are of course more convenient... but they do indeed force us to go faster. They speed up transactions, reduce queues, and eliminate the need for cash.
I'm happy I can buy stuff online, but that in turns also makes me consume more.
You're speaking of some of cash issues... but have you thought about impacts on the the homeless of a 100% cashless society?
They only free us from doing stuff like going to an ATM to get cash (which means getting in my car where I live). I can choose how to spend that time, maybe I want to spend it going for a relaxing walk around my village (which has no ATM).
Buying online doesn't have to make you consume more - it remains up to you how much you choose to consume.
A 100% cashless society is off topic. I'm not saying we should be 100% cashless but I would like to see electronic payments accepted everywhere (not necessarilly exclusively) - the author mentions Germany which is a real pain with some places only taking cash.
