Yes, but a baseball card is just a piece of paper with some ink on it. It's only trivially harder[1] to replicate than a pointer to a JPEG. We have already established that sentimental value + proof of provenance suffices to yield basically any market price. Take this concept to its logical conclusion, and you get NFTs. [1] At the price levels we're discussing.
Those are some of the means by which we arrive at price.
