There is nothing magic about the current from a rotating generator that cannot be exactly replicated by an inverter that synthesises the same waveform and produces it with power semiconductors instead of a steam engine. Especially

Exactly.  And "pull" in the required direction.
The challenge would be the distributed nature of the system components.
A large mechanical generator is a "big elephant" that can exert a lot
of influence.  Small individual (e.g., residential) would require
more coordination (and reliability).

domestic single-phase inverters already incorporate enough capacitance to buffer the PV energy supplied to them, so as to supply a sinusoidal current to the grid, and this storage allows it to shift the phase of the current relative to the voltage however required in order to help stabilise the system, if only it were allowed to and required to by regulations.
