What is good about money?

Morbius continues (private):

Flipping this around, what happens if you start removing properties of money from the notion of exchange:

• Remove the concept of a commonly-defined value (market value) of goods or services. What's the basis of exchange? How does efficiency of commerce -- the time to transact a given exchange -- respond? Note that fixed "price tag" retail was an invention of 19th century New York department stores which offered "no-haggle" sales, for efficiency, effectively. I'll note that this is a market and not a strictly monetary function, but it's one you've highlighted above.
• Remove the concept of a universally (or widely) accepted medium. Now any transaction must begin with (or include) a step in which the medium of exchange must be agreed upon. Including its notional value.
• Remove the notion of fungibility. If given coin or banknote is not equal in value to any other, then each token must be individually (or collectively) assessed.
• Remove the notion of money as having any commonly-agreed-on or stable-in-time value. Now any exchange must include an assessment of "what is this worth to me vs. you", or "what will this be worth next week/month/year", especially for recurring services.
