High Fee Environment's Impact on Coin Join and On-chain Privacy

Just a thought I had this morning on the long term affects of high fee environment on bitcoin on-chain privacy. I don't have any deep insights but it would seem that as with most of this discussion about fees lightning becomes more and more important.

What are your thoughts. Regardless of BRC-20/ordinals longevity eventually we will have sustained high fees as more of the world on-boards to bitcoin. With that in mind, how will we use bitcoin in the most private way? My answer is lighting and eCash tools that are still evolving. What are your thoughts?
