You'll have seen those TV programmes where record collectors/music enthusiasts wax lyrical over their latest vinyl find, whilst playing it on an ancient portable record player!
They are immersed in the music, and seem oblivious to the fidelity of the reproduction.
The connection to Planet Earth performs at least three safety functions:
1] to keep your AC power system potential near Earth's in the event of a nearby lightning strike.
2] to keep your AC power system potential near Earth's in the event of power company high voltage failure event.
3] to keep your AC power system's Neutral potential near Earth's. For safety near swimming pools, damp floors and such.
4] I think that there is another.

To act as a sponge to soak up all the nasty noises? Oh, no, sorry, that can be done with a box of God knows what
This thread is inspiring me to reboot my study of interconnects made from bananas or from mud. Remember? The ones that people had a very difficult time distinguishing, even from the original recording.
Years ago, when I got my Audio Precision 2322 I ran a quick test trough an apple to have something to measure ;-) I found a significant drop of level even into 100kOhms, rolled-off high frequency (a few dB) and lots of harmonics on the order of 1% or so. Never checked the impact in a listening test, though.
They care about the performance and the mix, mostly am "I" loud enough in it. The sound quality is down the list. And can some one who spends most of his listening experience at the wrong end of a trumpet, sitting on a cello, or listening to a Marshal stack at 11 really know what its supposed to sound like in the audience?
In the interests of safety, let me state the situation in the UK.
The latest edition (the 17th) of the IEE's Wiring Regulations states that it is no longer permissable to add an additional earth rod to a domestic ring main earth.
To comply with the new regulations, an additional earth rod must not be connected directly to the mains earth, but may be connected via a device which allows only any RF present in the earth circuits to be routed to the earthing rod.
These 'RF Router' devices are commercially available.
Also a significant problem in my tests. That meant more gain and more noise, which some people did hear vs the original file. I hope to do better this time.
I didn't have the roll-off IIRC. Didn't check distortion, or don't remember it. Even running signal thru copper, potatoes, mud or coffee it was very hard to tell the difference by ear.
I have worked with musicians in recording and broadcasting studios for many years. I can't actually recall any of them claiming to be able to hear a difference between cable types apart from defective cables that were either noisy or discontinuous!
The bizarre beliefs of the audiophool fraternity - akin to religions - are based on nothing more than faith and confirmation bias. They paid $500 for a cable, so it must be better than the one I made for $1.50. They even refuse to believe the evidence of their own ears in blind testing - the tests are flawed, or we cheated in some way, or our cable didn't really cost $1.50, or the connectors on the amplifier were defective, or the moon phase was waning....... Anything but accept the reality of the daylight robbery committed by most "audio" cable manufacturers. 😱
Most of the audio cable "makers" don't actually "manufacture" anything at all. They just buy cheap Chinese cables and then label them with their own product names and multiply the price many times. The Chinese factories will even stamp your brand name into the plastic moulding of the plugs for a cent or two! 😉

Maybe you could use a better methodology, next time? Or if it's just for fun then just have fun & direct people to be wary about drawing any conclusions!
Because for every audiophool there is a sciencephool 🙂
Or maybe you want to talk about the insensitivity of forum run blind testing?

I had a quick scan of the earthing section of the regulations but didn't see this, can you tell me where it is please?
Did you actually do the test or even read the thread? Or just shooting in the dark?
