not sure if you're being sarcastic here. It is true that journalistic heat has been known to help re-arrange development priorities, and not being able to pay your bill seems like a potentially significant problem.
That is true however how do we think it works if you loose your credit card ? You would call and cancel. This would be the case most of the time as none is going to trust website to cancel the card. You would need a human intersection here.
IMO you are less likely to loose your phone then credit card. We think of actual physical credit card only when we need to pay with it. 99% of the time it is just sitting in the wallet being all useless. Phone is something we are using every 5 min or more so chances are less that one would loose phone like that. Now if you do loose it, and hopefully it is locked then no one can use your card. However one can just cancel the card by calling it from borrowed phone or something like that.
I think the article's point is that you cannot pay your Apple Card bill, not that you cannot pay any bills. Of course losing something means you cannot use it.
