A kayak is a "thing", but it's the gateway to an experience. If I buy someone a kayak, I don't intend for them to just hang it in their garage and look at it. I expect they'll actually use it.
If I buy someone a board game, I expect they'll play it with other people. If I buy someone a food basket, I expect they'll not only eat it, but share it with their family and make a memory around it.
If I buy someone a $1 toy from Dollar Store, I expect they'll play with it for a few minutes, and then throw it away. Yes, that was still an experience, but it's a pretty hollow one, and so it's just a "thing", though I suppose there's still a chance it could generate good memories.
OTOH, pre-painted figurines... I just don't see how they create an experience. They're literally just there to look at. They might remind you of an experience you already had, but they don't create or enable experiences.
And by extension, you could apply this to almost all art.
And I definitely don't think people should stop buying (or producing) art. I end up thinking about the advice sometimes, but I don't follow it.
