Well, I've been thinking about it some, and I don't see how blockchain is even a solution to #1 in the first place, much less presumably the only solution. For data collection concerns, the most natural solution is of course to simply see that data is never collected in the first place, and this can happen via legal means (e.g., GDPR) or technological means (don't include unnecessary sensors).
