From a purely selfish standpoint, I would not want to use this system, because I don't want advertisers, insurance companies, malcontents, stalkers, debt collectors, busybodies, three-letter-agencies, data brokers, or any other random with an internet connection to know that I spent money at a hypothetical STD clinic or received money for participating in a scientific study.

This plan introduces a huge number of of unknown unknowns, where right now, we've got a pretty good idea of how widespread the corruption is, the forms it generally takes, and what, if anything, we can do about it. And since past behavior is the best predictor of future behavior, I can look backwards to see how behavioral data is abused right now, and say with complete certainty that it would be abused more under this system.

No thanks.
