I keep hearing "build a thing that solves a problem" and I wonder

Hi, I've been reading on this sub and others about how to either come up with a good idea or validate the one you have, and I invariable see the answer that your idea must solve a problem.

And it makes sense hundred percent.

However, I'm wondering if there are no cases of successful businesses beyond that in which solving problem is not exactly the point, or it is more fuzzy to frame it like this.

To clarify, there are for example luxury brands...which sell a woman handbag for amounts that regular people can't understand. They don't seem to solve a problem. In any way, not a practical, immediate problem.

And there's also the collectors type of businesses, where someone needs to have something as part of a collection...that doesn't solve a problem either.

So my point is, if I have an idea, in which people want to buy something to satisfy for example being part of a group, with a certain culture, or helping the nature, or something like this, in which they feel they do a change but they themselves don't benefit directly, does that have chances to work?

And how do you call this other category, which books talk about it? The need to change something or to show you belong to a group.
