In a potential future conflict, high-value GPS satellites risk being hit or interfered with. If this happens, the loss of GPS could have severe consequences for communication, navigation, and banking systems in the United States.

Banking?

accurate timekeeping? that's all I can think of for trading at least.

Yup, you're absolutely right - GPS is used in high frequency trading:

The worry isn't that HFT stops working. It's that it causes a failure state that brings down the legitimate parts of the financial sector.

Like how we're not worried about AI pilots malfunctioning and being grounded, the same way we'd worry about AI pilots malfunctioning and bombing humans.

I worked in a place where the machine room had a network time device that connected to an attena getting gps reading to give time to all the other hosts. Im pretty sure any ntp server a host has configured is only a hop or two away from a device like this.
