I hope your right, but I'm concerned that blockchains still rely on the core developers. Very few people really understand the protocols, and even they don't audit their nodes' code. You don't have to trust a central database, but you DO need to trust the code that runs the distributed database.
This need for trust demands politics, and that's why we have Bitcoin's crisis de jur.
A solution for this problem will be general libraries which you can build blockchains with. But I agree on that maintaining a blockchain needs governance as well.
