You are not following the point I’m making:
The account you buy on the darknet works because the rest of the internet already associated it with an identity. That means law enforcement has cause to investigate the new user for impersonation or id theft. It doesn’t matter if they can’t get you for id theft or impersonation on a technicality, they’re already investigating you at that point! Law enforcement attention is what you don’t want!
It’s like using your neighbors car with an expired tag because you don’t want to have your car show up on the highway cameras.

Physical movement can be tracked by cameras. All digital transactions are tracked by virtue of the way the internet works.
When you put your trust in digital transactions you are putting your trust in the cryptography that hopefully underpins them. With recent regimes of harvest now decrypt later, you are putting your trust in both the perfect forward and quantum/parallel resistance of that cryptography.
Just some food for thought. Sending cash might be a smarter choice than you think.
