Everyone wants an untrackable unblockable currency that is out of government control until the day it is used for things they don't like, then suddenly "government please control this!"

Where did you get it? Purchased/transferred? Where did they get it? What else did the person with that wallet do?

If the answer is "mined", even then, you have to actually do something with it, right? Buy something? Where is that something shipped? At worst you'll have to pay customs on it, and have it actually get through customs. At best, your address is in a database now.

Have it shipped somewhere obscure? Video cameras are everywhere. Have it shipped to someone else's house and steal it off their porch? Again, cameras everywhere.

Not have a physical item? Just a service? That's pretty much the closest you'll get to anonymous money transfer and full usage (along with whatever VPN you prefer).

Cool that was a fun mental exercise. Now everyone tell me why I'm wrong!
