I have another problem with your hypothesis. According to Kirchhoff's law, the current going in is equal to the current going out.

Kirchoff's laws apply to DC (or steady state AC) circuits with conductors, that is, with discrete points and nodes. It's not entirely clear that you could apply them to regions of space (although, fundamentally, that's what FDTD type models do). Kirchoff also isn't so easy to apply to cases where the propagation speed of the wave is important (i.e. transmission lines)



  According to Ohm's law the current is going to take
the path of least resistance.

Not precisely.. the current will distribute in inverse proportion to the resistance. And, again, when you start talking about time varying fields with some significant physical extent, "resistance", which is a DC phenomenon, doesn't tell the whole story.
