I didn't mean Robosats. People are sending money from their bank account to random bank accounts to buy "non-KYC Bitcoin". Every transaction is a paper trail and you don't know who your counterpart is. It could be my Mum, or a terrorist, a cartel member, just another pleb or a sting. You simply don't know but you're establishing a financial link with your counterpart.
Plus, at least here in the EU, cash transaction limits, bank transaction limits (and withdrawal limits) are getting tougher and tougher. It used to be 10k no questions asked. Now it's something stupid like 1-3k. Anything beyond that raises questions.
So yeah having real life contacts and building up that trust with them is important since that takes time and like I said, most of us will need such cash networks rather sooner than later.
