This sounds like homework from an undergraduate philosopy course. "Responsibility - a necessary evil? Please discuss".

I'd certainly like to think that was the case, that you could travel round the world for as long as you wished and have no responsibilities or cares but I suspect there are few people like that (and I've never met one). Everybody has responsibilities - primarily to themselves but inside there'll be a list of others - family members, friends or whoever, or cares about something, even if it's only whether the front tyre is going to last until the next town. As the saying goes "no man is an island, entire of itself"

Being a free thinking liberal () I'm willing to give most people who decide, of their own free will, to spend time traveling by whatever means they chose, the benefit of the doubt. Some may be undergoing a personal crisis of existential angst about the nature of freedom, others may just need some time away from years of overwork and underpay. Still others may be using the trip as part of their future - Ted Simon did ok out of Jupiter's Travels. Walk a mile in a traveller's shoes and then decide whether he's a shirker or a saint.

The reality is that most people who leave, Laurie Lee style, do so still tethered to their previous life. Sooner or later they reach the limit of their resources, be it money, time, enthusiam, physical wellbeing etc. and have to make decisions about where they go / what they do next.

As for the list of normal attributes - career, family, house etc, almost all of them are not easy to get. Where do you "get" a wife (or husband)? I've had 2 1/2 and it's not been by design. Good luck as a first time house buyer in the south of the UK at the moment particularly if there's only one of you.

Career is interesting; the word that is. Using it like "I've had a career in sewage disposal" isn't quite the same as "I've had a career in vascular surgery". The latter suggests something you've had a hand in, climbing to the top of a greasy pole. Come to think of it so does the former. If you can think of an angle, a reason, a lifestyle that sits well with you there's no reason why professional traveller isn't as good a career choice as any other. The fact that most people can't make it pay doesn't disqualify it. A few people make money out of things that many more pay to do. I do. I make money out of that, quite literally.
