I’d never ever use cash for a private sale - of anything — either regardless of whether it was $100 or $100k. For a large number like $10k, bank transfers work well. For smaller numbers, instant transfers are cheap and nearly 100% of people use them here (and importantly the same service - so I know I can instantly transfer $2 to anyone at any time for free). When I place an ad to sell a used something for €50 I don’t expect to get cash for it and the seller probably isn’t expecting me to accept cash as payment either. I haven’t used a banknote for probably 10 years now. I haven’t even seen most of the banknotes in circulation here. This isn’t all positive (for privacy and resilience in a crisis), and the fact that I wouldn’t doesn’t change the equally important fact that I want to be able to do it. And that ability is of course in peril here. But it doesn explain the situation quite well wrt to what the real impact of laws like this would be.
