If we use a capacitor that has a decoupling capacitor, so shunted to ground, then why for a DC source do we say the capacitor acts like a short at startup (t=0) thus having a high inrush but according to the top paragraph a DC source has a 0 Hz frequency so it has a very high impedance. This clearly is a contradiction.

Electrolytic capacitors may become permanently damaged by excessive peak currents, which will definitely occur during short-circuit events. The reason is that (a) the internal resistance will cause a momentary, but large power dissipation (heat!) and (b) the distribution of the current spike inside the capacitor will not be formed evenly across …
The short circuit in the secondary coil keeps the magnetization of the transformer core close to zero, making the primary coil behave mostly as a short circuit (or rather low resistance) as well.

The power of even the largest high-power laboratories is not sufficient for testing the majority of HV circuit breakers. Therefore, alternative test methods, such as synthetic tests, unit testing method, and multipart testing method (see Sects. 11.5.3, 11.5.4, and 11.6), are in use to impose adequate current and voltage stresses on circuit breakers.
Short circuit current is the flow of electrical energy that results when the insulation barrier fails and allows current to flow in a shorter path than the intended circuit. In normal operation, the impedances of the electrical appliance loads limit the current flow to relatively small values, but a short circuit path bypasses the normal current-limiting load impedance.
