All great points. And I agree with you on most everything.
I care about the major complicated projects succeeding, e.g., 0x, Golem, Augur, Aragon, to name a few. They can go the DAO route, or I can do my part in helping. Help me get in touch with more projects if you're connected.
Open sourcing right off the bat will have the opposite effect. If it works at scale, we will be pitting the attackers against the developers. I would rather get this tool in the hands of developers first. I welcome other people developing the same :) - better yet: I've already developed a version, come help me make it useful for the community.
