Achieving safety+privacy is great, but in most cases you shouldn't worry about your BTC being traceable on the blockchain(unless you are doing something illegal).
That is not always true, privacy is important for so many reasons, even if you are not into anything illicit, one of the things i learnt when i got into BTC is how to keep my funds private, don't talk too much about my BTC's and use provacy solutions when i have to. My point is that, it is wrong to believe that only people into illicit business have to worry about privacy, that is what the government wants to establish with the whole bullshit of 'clean' and 'dirty' coins, and in that way attacking BTC's fungibility.
