It could also just be women thinking, "I'd like to visit _____ when I'm able, I want my partner to go with me." Working in a passport office, I've met a shocking number of men who have never left the US (or sometimes even the state) by choice. Then their wife or girlfriend wants to go to Mexico or something, and they come in talking about how they're only doing it for her and they'd never travel if it was up to them.
Anyway, I'd consider traveling one of my hobbies even though I can't afford to do it often - plenty of time is spent planning and looking at things to do, so it goes beyond just the few days of the trip.
I've met people who are extremely happy living in their small town life doing small town things, then get angry or confused why anybody would want to go someplace "exotic".
Maybe "travelling as a hobby" as a women's preference with regards to men is at about it being a man's openness and ability to deal with totally different environments, disposable income, time availability and possibly foreign language skills.
I'm one of those people. I've never flown, rarely leave my state. My wife wants to travel, but we haven't yet. I, personally, have no interest in it. Just like sports and most popular movie franchises. I just have no feelings about it at all. It seems like a huge hassle.
If they flaunt it with their fancy cars and designer clothes, I think they're gross.
If they look like a hobo but are highly educated about finances... Aaaaay bay bee how you doin? Wink at me, you economist with a 401K who ties her hair up because she hasn't showered in days because she was doing data science. Spit in my mouth, you engineer with a diverse stock portfolio who wears the same hoodie you wore in college because clothes shopping is hard and you want to focus on optimizing your CI pipelines. Choke me, you tenured professor with a mature retirement fund who dedicated their life building physics engines to teach grad students.
It's unclear what countries this poll includes, having minimum paid leave is the law in most of the world. There's also quite a few careers that involve forced time off.
If you live at home or are technically homeless it doesn't really matter. If you can save up a bit and have a charismatic personality you can go far, especially if you're willing to pick up shitty temporary jobs in places where you go. I had a friend who would do this all the time and periodically return home to work at a reliable job while living with a friend, save up more, then fly off to somewhere for a few months.
"Fun" fact, this is actually why my mom has no interest in camping as an adult. Her family was homeless a lot when she was a kid and her mom disguised it as a fun extended camping trip. The kids bought it for the most part, because the family really did camp for fun, and they were used to fishing for dinner and things, but she said as she got older, she realized things like the month long trip in November were because they lost their housing.
For the vast majority of you, long travel is required to get to somewhere you can backpack. And the the gear and foodstuffs is expensive also. And judging by the damages to the environment that some inconsiderate people leave these days, I'm not sure that you should be allowed to. (I'm getting sick and tired of picking up garbage and hauling it out of the forest I live in).
"Backpacking" can also mean couch surfing and staying in hostels or on park benches. In the early 2000's, it was a really popular way to travel across Europe (at least among rich white college kids)
Or be in a religious cult like Mormons. Of course they will send you to a foreign country and confiscate your passport until your 1.5-2 years are over.
I remember listening to some pop song and realizing that it was basically "You love me 'cause I'm rich". Do you like trashing hotel rooms, going places you have never been? I don't remember what song it was or the exact lyrics, but I just hated the guy then and there.
