Of course they have a market. Not a market of real estate bubbles and NFTs, that's for sure, but a market of skills and cooperation. They may not have much job specialisation (or they do, difficult to tell without contacting), but even without, different levels in experience and physical fitness will make that a market nonetheless.

And what level of experience we are looking at! Remember the 10000h rule? Imagine a group developing exactly one skill set since childhood. Trained by a chain of ancestors following the same path that would make the Bene Gesserit blush.

This would all collapse under contact. A few years of handouts and/or one-time trades and nothing of those abilities would be left. And those years would be far too short to find a place in the new (to them) market above that of beggars and thieves. They would have trouble even working as prostitutes not knowing the cultural codes around that.
