I'd call that a feature rather than a bug. I am absolutely able to buy and sell items traceably with other people though. For example I recently bought a house. The transfer was facilitated by my solicitor and recorded in a central government registry. > It also doesn't allow for arbitrarily large transfers. Transactions of many millions of dollars are routinely made using existing digital banking technology. My personal account has a 10k/day cap due to money laundering rules but that seems fairly sensible. I can call them up and have it raised for one offs.
