A lightning strike involves 100 million or more volts. If lighnining strikes in the vicinity of one of your grounds then a voltage potential may develop between these two grounds. You've now got (gasp) a ground loop. Essentially current will flow between the grounds. Care to guess what the lowest impeadance path could be? Yup, right through your rig. You've perhaps eliminated the ground loops in your system, but have created a potentially more dangerous ground loop.

Remember also that this catastrophe could also result in a fire. If the insurance inspectors discover your grounding scheme I would imagine it's possible that they'd void your fire insurance.

There's a better discussion out there than the one I've included below. It shows how lightning travels across the surface of the earth and its effects on grounds. I can't find it now, but if I do, I'll post it for you.
