Is it necessary for a photographer to take a tripod when traveling?

Not necessarily. It depends on what you want to shoot.

If you want to take pictures of the scenery, a tripod is essential. For example, if you want to take a long exposure, there is definitely no way to hold it, and the picture will be empty in an instant. So is the Milky Way starry sky, and a tripod is essential. Tripod is almost as important as camera in landscape photography.

Do you need a tripod to take a portrait? If you need a flash, you'd better bring a tripod and set a flash. And if you want to take a selfie while traveling, then a tripod is definitely essential. Fixing the camera with a tripod with a delayed shutter or a wireless shutter can help you take selfies more conveniently when traveling. Then if it is mainly for others, the tripod is dispensable.

And if you are filming a documentary or traveling to sweep the street, wearing a tripod is too conspicuous. It is not recommended to wear it, although the tripod has self-defense function in this situation.

In addition, I suggest that people who like photography go out with a small tripod and put it inconspicuously in their bags, so as not to have a shelf when they really need it. You can bring a small octopus, hundreds of grams, which is also convenient to use, isn't it?
