As the person said, it is not a problem with crypto because there are indeed solutions to the problem. The tool you are referring to are the set of crypto currencies, of which there are many, which do not compensate data handling.
The point I'm trying (and failing) to make is that if a solution to a problem is reliably mis-used by its users, then it's not actually a solution in practical terms. The problems in this space are ultimately social, not technical. Success is measured by usage, not passing tests.
