This is actually a subject dealt with widely in the humanities. The Work of Art in the Age of Mechanical Reproduction is a good start, for instance. It does seem odd for art to be valued by the market, but there are clear ways to construct standard valuation (based on utility, etc) around it.

  some computer and printer somewhere can easily reproduce the piece if I ever need it again [...] well-defined manufacturing cost

This is not as straightforward as some might think! Some people agree with you. Some don't. "Fake" is a spectrum as well. Is it a reproduction of an original work, or an original work falsely attributed to a particular artist? In the second case, if the quality is high and scholarship has emerged around that work, is it "less valuable" to own after it is revealed as fake (for one individual, not at market prices) or is it in a sense more interesting? Is it perpetrated to be real or simply a print? Even if it's an authentic creation of the artist, was the work been authorized outside of their canon in a less official way? What about photographs, and later editions of them (by either the artist themselves, their estate or family, a dealer, etc)? Check out Richard Prince and his "decertifications" of paintings.

Startups offering blockchain solutions to this landscape, of course, are emerging. But they face the same problem everyone does in that market: how can physical assets, and their movements, be indisputably registered to a blockchain?

I suppose this is true, very interesting. A piece (real or not or unknown) with history, can become (de)valued in its own right.

For example, I think VeChain and Modum use physical ID chips, but I don't see how they solve this problem. It seems like a tall order to create an injection between physical assets and digital ones. I could see how this would be done if the physical assets were fungible and centrally sourced, which is only going to be the case with certain physical assets.

How would people register those assets to the blockchain? No one in the world should be able to register my laptop, because they don't have it. It would need to be derived from physical measurements, but this is a can of worms because the measurements can change; physical matter is not immutable in the way that digital matter is. Coupling the two seems like a tall order, or maybe I am small minded.
