> And when we inevitably leave our card somewhere and we need to get home?
How is this different to cash? I also have Apple pay on my phone and watch.
> Or it's blocked for some random reason
I have a couple cards. Also, I've been cashless for 10 years across three countries and this has never happened.
> Nevermind the services that just don't take cash
Assume you mean card. Not a problem in many countries including Australia, New Zealand, and the UK. I travel a lot, remote, even random middle-of-nowhere merchants accept card. From a business point of view, cash-only makes zero sense. Why would a business turn away people who want to give them money?
> or the fact that their card reader might be down
Never had it happen. A couple of times the payment network has been down, and these terminals seem capable of making the transaction offline and syncing later.
If you're from a country where any of these are legitimate concerns for you, it doesn't mean cashless is bad - it means the systems are bad. And they can be fixed, again, AU, NZ, and UK (and more, I'm sure) are proof. Haven't carried cash for 10 years and it doesn't occupy a single thought.
