That's not only mistaken, but typically a violation of current code, at least in the US. Multiple ground rods are now required at a service entrance and if that's not part of an installation now, it will almost certainly be required if the service is ever upgraded. Also, the length of the connection to the ground rod is not usually the determining factor of the safety ground's impedance - that's established by soil conditions. Moreover, a household's ground isn't really through those grounding rods - those are just the safety grounds. The real ground is back through the utility connection - as required by code - unless you have some type of electric problem or malfunction.
Power supplies already contain robust protection that makes most surges (including mythical ones from household appliances) irrelevant.That's absurd. Few devices contain serious protection against power surges. And I'm not sure why you call appliance surges "mythical" when they can be both heard and measured.
An effective protector must connect low impedance (ie less than 10 feet) to single point earth ground ... Effective protectors (as installed for free on phone, satellite dish, and TV cable) always have a low impedance connection to single point earth ground.
