The idea that an email asking for a blockchain currency is somehow more difficult than a dead drop of physical currency is absurd. While there are some merits, this type of value exchange is a dangerous vehicle for facilitating human exploitation. We need to start talking about that fact more, instead of the fever dreams that those of us in the free world somehow live in some faux-totalitarian state, simply because you can't legally purchase MDMA or cocaine.
Evil people use neutral tools for evil purposes. They have been since the beginning of tools.
So stop trying to slow the advance of technology just because some evil people can use it too.
Monero seems much better suited as a weapon against real totalitarian regimes. If it is illegal in both a free and unfree society, then it will only have a practical purpose in the unfree society, whereas the free society will have plentiful alternatives.
And if you receive that $10k in cash, how do you deposit it without the same risk?
Monero is light years easier for law enforcement to find kidnappers (exchanges, honeypots, network access) than cold hard cash.
Was there a plague of kidnappers when the world used 'absurdly dangerous means of value exchange' like paper currency and gold?
edit: my reply was before you edited to discuss physical currency. $1M in $100 bills is 22lbs. Hardly a deterrent.
