A complement to the framing, with the standard textbook definitions for anyone who wants them:
Three functions (as in e.g. the Bank of England's 2014 Q1 Quarterly Bulletin article Money in the modern economy: an introduction): medium of exchange, unit of account, store of value. The post's "measure to talk about value" is the unit-of-account function, and the tape-measure analogy for inflation is that function failing.
How central banks measure it (Federal Reserve definitions, https://www.federalreserve.gov/faqs/money_12845.htm):
Monetary base (often called M0): currency in circulation plus reserve balances banks hold at the Fed.
M1: currency held by the public plus transaction deposits (checking and other very liquid deposits).
M2: M1 plus small time deposits (under $100,000) plus retail money market fund shares.
Worth noticing: most of M1 and M2 is bank deposits, not cash. So in the measured sense, most "money" people use day to day is a liability of a commercial bank, which fits the post's point that money is a coordination tool more than a physical thing.
