What does the rural proverb "Go out for a thousand miles without wearing a needle" mean? Does it make sense?

The literal meaning of "going out for thousands of miles without needles" means going out for a long journey without needles and other things, and extending out without anything too delicate, trivial and generally useless.

In the past, the traffic was inconvenient and it was not easy for people to go out. The main means of travel are cars, horses and donkeys. Many people even walk, and sometimes they have to walk for a long time, ranging from ten days and a half to one year and two years. So packing before going out has become a learned thing. The purpose of "going out thousands of miles without a needle" is to be light and practical, and to bring as little or no such unimportant things as "needles" as possible.

Moreover, every household has such necessities as needles, which are not easy to use or break. When you are away from home, you can borrow it from others if you really need it. And the needle is too small, easy to lose, difficult to find, there is no need to carry it with you. Besides, needle and thread is usually considered as something commonly used by women, and men can't use it. Men who go out "don't give injections" not only warn them what to do, but also remind them to always remember that relatives at home are looking forward to their early return.

For us, transportation and shopping are very convenient now, and needle and thread are generally not needed, so we can't think of it. It seems that the phrase "go out a thousand miles without a needle" has no contemporary value. However, I think the truth is instructive: for people who travel on business or long distances, travel lightly and bring as few unimportant and generally unnecessary things as possible so as not to cause unnecessary burden on the trip.
