you can still do lightning (which will mix it), pool it or picrel (picrel is from >512358881 (fucking shit)).
but yes, the chance of your coins somehow being rejected or stolen without goods delivered is a possibility. but in any type of trade you need some type of enforcement or well... trust.
at the latest when you meet the person to exchange crypto, you lose a good chunk of anonymity anyway.
i don't see crypto as some alien tech that allows some form of supremacy. you're still bound by societal limitations and what one man alone can do.
what it does allow is create a network of settlement based on a technical arms race rather than a militaristic one.
if the world ends up deciding to trade/settle in crypto then the nation with the better tech will dictate norms because it will outmine the other one. and yes it can always escalate into savagery but it's unlikely that a poorer tech country somehow outshines the other nation in militaristic tech if they can't handle algorithms.
and yes, you/ that nation can always hard or soft fork which makes these debates kind of pointless. it's a method of settlement that doesn't need supervision and the security of its transactions is intrinsic.
