Each threat has different incentive structures and different kinds of impact and these are complex to understand and evaluate. So while this have been discussed on the forum I doubt we’ll get a full understanding of all the issues and it’s pros and cons. It requires deeper clearer thinking than we get here, although there’s no reason not to look at it again, maybe in a dedicated topic so that can be referred to if it comes up again.
For example, it is not true that being able to mint DBCs only has a profit motive. That could be used to disrupt the network by destroying the economy, rather than only milking it gently. That’s not hard to see but been missed immediately in this discussion.
As for “if we can’t trust the network to do this, can we trust it to protect other data?” that’s a valid question, best explored by asking what are the threats for the other data, the incentives, rewards etc for attackers. You can’t answer it with yes or no, but you can look at where the network is weakest and then decide how to make it secure enough for each aspect.
However, securing data isn’t an afterthought, the whole design has been created, adapted and changed over time to get a balance between security, efficiency, cost etc. If a new feature is then proposed, like having Sections mint or control vast sums, you need to look specifically at that. It doesn’t to throw everything you’ve done so far into question.
So there’s no need to suddenly doubt the suitability of the network to store other data. That’s not changed. By all means re-evaluate it, that can do no harm, but it doesn’t really belong in this topic and hasn’t suddenly been thrown into doubt because a different kind of threat is seen as too risky.
