if it is already traceable I think it is not bitcoin at all, the main feature of bitcoin is you can transact anonymously, so if it will happen , many scammers will be afraid and they can be lessen, but the traders and users of bitcoin will be lessen too, this is my few cent, I dont have any problem if it will be traceable but it could be bad for some other people.
Actually bitcoin is already traceable and the simplest thing you need to know is who the holder of the address and if revealed you can see where they are sending their bitcoin into, even most of popular exchange address nowadays have a label name which make it even simpler. There are also tools to trace what address connected to each other so yeah it's traceable and transparent even surpass banking transaction. The fact that it needs to know the ID of address holder even before we can trace I think is enough to not harm people's privacy.
