Not being registered on centralised exchanges in the first place is a great   start as you aren't in huge databases that are future data breaches waiting to happen. Obviously coinjoins were for forward privacy but that's not ideal anymore. This is where monero pairs beautifully with bitcoin for spends with atomic swaps as it's so much less of a headache than privacy using lightning. 

You can argue that all that can be flagged also but if anyone is doing anything nefarious then using bitcoin at all is stupid lol.
