Agreed.
Cash is dark money and it is important that people have access to dark money in the digital age. History has demonstrated to us what crimes surveillance regimes can commit when they go unchecked. Under authoritarian systems, dark money will always be vital. It is my hope that Bitcoin can compete with Monero on L2-L3's in regards to dark money. The base layer obviously cannot be both a store of value and dark money at the same time. As such Bitcoin and Monero occupy different niches.
