An impossible goal. You could be endangered in any of those situations by someone playing "The Knockout Game," or with a knife, or strongarm robbing you, or carjacking you, etc. That doesn't require a firearm. So, your condition isn't met by ending the 2nd Amendment.
Mass stabbings occur regularly across Europe.
Knives kill more people than rifles like the AR-15 each year, even this anti-gun site grudgingly admits
A number of posts led readers to believe the Federal Bureau of Investigation's crime statistics implicated knives as far deadlier than rifles, but there are a few issues with that assessment.

Handguns are by far the most common murder weapon used in the United States, accounting for 7,159 homicides in 2023.

While handguns (aka pistols) are a serious issue, rifles are not. By the same token, knives simply replace pistols much of the time to no net difference.
Access more difficult how? Demanding they be kept in a gun safe? Try enforcing that.
Eliminate private sales? That would be very difficult to do too.
Require liability insurance? Try getting that past the courts. That is putting a monetary restriction on a Right. It would be no different than requiring liability insurance to speak in public. How would that help? If someone is using their firearm responsibly, they likely already have something like homeowners to cover an accidental firearm injury. On the other hand, a criminal using a firearm illegally wouldn't be covered in any case by insurance. The company would deny the claim on the basis it involved criminal activity. It'd be no different that if you burned your house down to collect. Crimes aren't covered.
You may say you have "no problem..." but you do. By all of the above you are penalizing that guy and doing nothing to the criminal who flaunts the very laws you passed to supposedly stop him.
I see no purpose to carrying 24/7 either but I don't begrudge or want to see such a person stopped from doing so if they are doing it responsibly. Rights come with having to endure the discomfort of others exercising them freely and responsibly in ways you disagree with.
