help regarding a led switch circuit

I have this circuit that turns a LED on/off but it uses too many components is there a reason for this?

That is an elaborate circuit, indeed, which includes an oscillator from DC (the logical inputs "1" and "0") since a simple DC voltage won't produce much in through the transfo.

Not the simplest way to produce a pulsing LED, so what is the circuit intended for, I could not tell.

Note that the time domain simulation does not exhibit any sustained oscillation, which is often the case with simulators, given the "perfect" symmetry of the mathematical model, while, in the real world, manufacturing differences between the parts could start and maintain an oscillation.
