For sure. That's a problem with public blockchains that we'll wrestle with soon enough. They are presented as being more private when in fact they are more public, and certainly once some big exchange is compromised someday.
I think we'll see more from private currencies like Monero, since they're kind of what bitcoin was marketed as. Cheap, private digital currency.
Why is this better?
Receipts on the blockchain is just another push toward purchases being "renting access" instead of "owning stuff I can resell anonymously."
