My point is that liquidity's value comes from its secondary effects of allocating resources more efficiently. It's important to have this awareness because increasing liquidity might not always be the best way to increase the efficiency of allocation.
Same with software. Software tools have value equal to (amount of things produced with them) - (value of things produced without them).
It doesn't matter whether it's the best way, just that it's effective. You typically get better results by applying many improvements than you do by just applying the "best" improvement.
And, liquidity isn't just about improving allocation.

Actually not. The value of anything is the benefit of said thing minus its cost. It's otherwise independent of the value of other things.
You may decide between two things based on their relative value, but that's different.
The value of farm equipment is in more crops being produced.
The value of liquidity is less clear. An upward sloping yield curve means people are willing to exchange more money for shorter term debt. That money can then be used to invest in the creation of more products. It's not until that point that it's clear what "real value" is being produced.
