Privacy is much more difficult than people think - when it comes down to technical details, it is required for privacy to be default, otherwise it simply doesn't work. Even when every single transaction is mixed, and values are hidden, there are STILL not-insignificant risks. If it is not mandatory then it is just not good enough, even for people that are not doing high-risk things.

>Monero doesn't enable privacy by default, but its known as a privacy coin. The first means that people could be unaware of the extra steps they need to take to get privacy

That is erroneous.
