The problem with your comment is that durable goods do in fact have many of the characteristics which are desireable of financial vehicles and assets: utility/value, portability, indestructibility, homogeneity, divisibility, stability, cognixability. (William Stanley Jevons, Money and the Mechanism of Exchange https://archive.org/stream/moneyexchange00jevorich#page/n7/m...)

And whilst land may not be particularly portable, land ownership is.

Other productive assets: metals, grain, productive plant, etc., may also have financial asset value. Also goods which aren't particularly useful such as fine art.
