>for a unity-gain buffer, the effective output impedance will be in the micro-ohms range

you're confused. supposing what you say is true, then a 1Vdc output voltage connected to a 0.1 ohm load resistor would give you 10A of output current.

that's never gonna happen coz in the REAL world, not your micro-ohm fantasy world, op-amps have output impedances in the dozens, or hundreds, of ohms, which will limit the output current to around 100mA.
