That seems useful. You forgot one of the most commonly touched items—phones and computers. I am gonna put tape on the back of my phone case and my laptop.
This is a good point, but for what it’s worth I don’t fully endorse coppering your phone (mine isn’t coppered). Several people have anecdotally reported it being uncomfortable or irritating on their hands, or receiving tiny cuts from the copper, etc.
Absorption through skin is incredibly low, but I do take the risk of open (if tiny) hand wounds seriously, and also generally try to reduce my total copper contact in case anything weird does happen, since this is not tested by time.
You touch these often, yes, but how often do you share them with other people? If all the germs on there are yours, maybe disinfecting it is not really helping.
But if you are constantly handling your phone it will reduce the value of frequent washing/sanitizing of hands, since anything you do get on your hands will transfer to your phone.
Although, I don’t know what the numbers look like for transferring virus when a touch occurs—e.g. if we look at a path like “handshake → touch phone → [wash hands] → touch phone → touch face”, how much of the virus is left after four sequential touch events like that? Perhaps this kind of secondary contamination is not actually a huge deal? I have no idea.
A powder called Glo Germ, meant to visualize germ spread, was still visible to the naked eye after 8 handshakes (but not 9) in an informal experiment by YouTuber Mark Rober. ( https://youtu.be/I5-dI74zxPg?t=346 )
This is my usual attitude, but given the evidence that coronavirus is very long lived on surfaces and reinfection is possible, it seems worth it to me in this specific case.

Some discussion of whether wearing copper jewelry causes unsafe exposure to toxic copper compounds:

Seems like the case for copper on door handles is stronger than the case for copper on your phone, laptop palm rests, etc.

I guesstimate the deal is not negligible.
