Honestly, I’m sorry to hear about your inability to get supplies, but my spouse bought some alcohol from Amazon to make cleanser for ourselves, as well as bag-friendly spritzers. Yes, there are extremes, masks and cleansers being bought up in bulk, but Americans need to care more, not less, about COVID.
As to risk, although individually my spouse and I are at low risk, we also have older family members that could conceivably die if they were to get infected. I work at a cancer care institution, although a non-clinical setting, and it is taken very seriously. The risk is not a discrete event like a car accident, but something that can escalate, from isolated cases to infected families to large groups to an epidemic. The risk is systemic, and can harm our most vulnerable.
As for cars, Americans are complacent about the risks of them, and they should become more concerned. Generally, people are complacent about everyday high-risks activities they believe they can handle, and worried about things that are extreme, unlikely, and out of their seeming control.
