By definition and code, a separate non-current carrying ground is required for all outlets. In every house I've lived in, the ground is a separate thick copper bar that goes deep into the ground (the earth outside the house) and that is the ground connection for the house electric system. How can this can be considered dirty, other than the dirt that the copper bar is earthed in?

You are kindling right? The problem with grid ground is that is shred with anyone on world. Well anyone in the world is not a big deal your neighbors is truly a big deal. The grid’s ground provides a return path for fault currents, so it your neighbor has a leaky circuit then you have it. All capacitive drifting of your neighbors you would share with them if they are closer to the grounding point then you – in a city what assurance you have? Any single impulse PS (including the PP2000) in any single computer of any other devise return a tremendous amount of dirt to ground – it is great if it have the path to Earth right there but in busy neighborhood it is not the case. Are you sure that your ground impedance is lover then the girl who below you uses an espresso machine and hair fan? Did you measure the impedance of ground in a regular public building? In the best case it will be sitting in the cold pipe and you can to 10 time lower impedance with your own properly driven into alkalined Erath rod. The point that I am trying to make is that common ground of public grid is public sewer the only defense for you to have lower ground impedance than anyone else. But it is not a defense but minimization of damage, the true defense is in my view is do not use pubic ground but use your own if you like me live in a center of city, like I do. When use my own ground then I always (!!!) had voltage between common public ground and my own ground (15 feet copper rod driver in pretreated backyard and 8Ga 30 feet cable from chassis of single-ended preamp which was is the only contact point with ground in my system).
