Unless this person was a police officer, and you're glossing over a lot of the story, you can obtain a new one at your local DMV and resume operation of motor vehicles...
No, my driver's license was from another country. It would have required either thousands of dollars to replace or re-taking the test in the US. Neither options has been something I can do just yet. I'll take the US test soon.
If you're going to victim-shame and tell me, <<oh you just nearly got shot, what's the big deal, just hop on down to the DMV! It's your fault you can't drive a car right now>> that's not exactly such as simple thing to do and would be seriously rude.
I'm currently 25 minutes walking distance from a grocery store (not counting the small convenience stores), I got used to just walking to it and buying a limited amount, enough for about a week. Driving is faster, but then I buy more, eat more and the rest goes bad...
I'm not sure about the data and large trends for this, but here's my anecdote: Right now Instacart is the cheapest way for me to get groceries. Someone with a gun took my driver's license from me a few months ago, my bike was dismantled by thiefs, and I don't live within walking distance of a grocery store.
Lyft/Uber there and back is $20. Bus there and back is $6 (but with added time and stress). Instacart is $5-6.
Yes, eventually, it will be easier for me to bike there or to drive there, but not right now. Right now the cheapest way for me to get a large grocery trip done is Instacart.
So maybe they could survive. Not everyone is in my position, but someone who works two jobs, doesn't have a car and lives far from the store...that could describe a lot of people in the near future.
