People who don’t desire anything beyond a normal, ordinary life, in my opinion, don’t even think about things like cryptocurrency mixers.
Here I categorically disagree. Every bitcoiner should think about BTC-mixers. Why? Because of the pseudo-anonymous nature of this asset.
Most people don't care about privacy, and they'll tell you they have nothing to hide. That's not true, but life is a lot easier if you don't care about privacy (until it's too late).
