Hi Saki70, I don't consider you being argumentative at all. You're asking good questions and this is a confusing topic.
I'm starting from the assumption that one will be following standard code installations as provided in most jurisdictions in the U.S., so pardon me being a bit parochial in my assumptions. "Code" requires the ground and neutral to be bonded to to a single common ground at the circuit panel and then to the grounding rod. What you describe does not match "Code" as I understand it, but I'm no expert.
In my last home, I had a commericial electrical company that understood hospital grade installations do the re-wiring of my circuit panel and install isolated ground outlets and cabling. They did so and the grounding at the panel was exactly as I described above: bonded to a common point at the circuit panel and then to the grounding rod.
