Consistency has really gone downhill in macOS, but thankfully if there are menu items for those actions you can override the binding in the settings app.
This is not an issue with Option at all. When you receive data from an external system, you should always parse it before making assumptions. By parsing I don't mean read property x as string, but make it a CustomerId for example, considering your constraints before accepting the value.
It's likely still not a Mastercard/Visa Debit Card, assuming parent is referring to (central) Europe. Offering subscriptions via SEPA direct debit in EUR would catch most Europeans with likely much lower transaction fees.
I wouldn't necessarily call it irrational. While there are far less incidents in nuclear power, their severity and long term harm are much greater while being very hard to get back under control as we have seen in the past. I would assume many would prefer to have broken a bone a few times in their life instead of a single shot in the head. This fear is very much understandable in my opinion.
I do not mean to imply that there are less fatalities from other energy sources, especially since those harming the environment might cause the end of us all. It's much like the fear of flying, it is safer, but if something happens you cannot run nor stir to the side, you are completely of control and the outcome will be most certainly fatal.
