> We need to move away from the term "monopoly" (which may not literally be a mono) and towards anti-competitive.
Anti-trust rules cover both, with a (often complex to apply, because of the kinds of facts that need to be analyzed, but relatively well-developed) concept of “monopoly” which ultimately boils down to whether or not substitution happens in practice rather than whether there is exactly one firm ina descriptive market. There's no need to “move away” from one to the other.
