Bitcoin still has its privacy feature but it isn't as strong as it was before centralized bodies had arrived. Before now, there has always been other ways to increase privacy like use of coinjoins which was introduced in 2013.
Satoshi understood a lot about privacy and its negative impact. He somehow knew that if Bitcoin's privacy was as completely strong as that of coin like the monero's, it would lead to more illicit activities using Bitcoin.

Exchanges must follow government rules and avoid trouble, so they might have to remove coins that offer completely untraceable transactions.
