Or learn to drive, at least. I don't think lack of a licence would stop you driving in a real emergency.
Note that this is how I evaluate my risk. I absolutely accept this will be an issue for people who live in places where getting transport might be a problem. If that's a problem here, civilisation has ended.
None of those except cooking are in any way "basic life skills". Least of all shooting a gun.
So, yeah, it'd take pretty much the end of civilisation for it to be an issue. If I had no money, or lived somewhere rural, the considerations would be different.
And not being able to drive has never been a factor for me in deciding where I want to go.
If I had any desire to regularly go to anywhere so remote that I couldn't justify hiring someone to drive me there, I'd learn to drive, but in 47 years that has happened exactly zero times.
I love in a city in a functioning society, not in a rural location or third world country, and my interests don't include anything that will see me end up in the middle of nowhere. That this might not be true for you does not mean it isn't true for me.
If I'd lived somewhere a car was needed, I'd have learned. It's not an ideological opposition to cars by any means. Occasionally I consider getting a drivers license, and then forget about it, because it's just never felt worth the hassle.
Like you I've just never felt that emotional association with freedom from a car. I think an essential aspect of that was growing up somewhere where I felt I had the same options without one.
