Edit: Happy to see the case made for why TC or similar should be there given the externalities. Maybe it is a good case, but I have not seen it.
Some example applications:
- User wants to anonymously donate to another country that their current regime is currently at war with.
- User wants to pay for an abortion without it being easily traceable.
- User with a public ENS identity wants to hold ETH on a private account that is not linked to their public identity. This might be for safety reasons, or another reason such as wanting to make investments that are not broadcast to the entire world.
The attack against TC is the US government saying "you are not entitled to privacy here, and if you even so much as try to seek privacy, you will be treated as a criminal and have all of your assets frozen."
If that is the society you want to have, I think you'll face an uphill battle. If you want no or very little policing of money, need to make probably some proposal to prevent certain things in other ways.
