Cash is not completely anonymous, but hard enough and not enough parties track it. Bills are serialized and you could take photos of coins and likely identify them based on scratch patterns.
Still, whole thing is saved by not enough people actually tracking it to that level.
And on other side, BTC tracks every single transaction ever. Which is also detriment, that is we keep everything stored forever in lot of places... Which kind seems massive waste.
