It’s not conservative so much as innately human. A society made of individuals who feel no shared responsibility to contribute to society is literal anarchy
As you point out, someone begging to fund travel certainly fits the description of non-contributor to society.
But many (most?) self-fund their ongoing travel, whether through odd jobs while traveling, savings from a previous stable employment, or "digital nomad" work on the road[1]. In that sense, they're just shifting a portion of their contributions from time period B to time period A, in the same way that spending during retirement works. I don't see how this can be described as "feel[ing] no shared responsibility to contribute to society" any more than someone who spreads their contributions more evenly over time: it's just describing the use of money as a store of value.
A lot of us think it’s time to design new values and beliefs.
