Yes, I've mentioned that elsewhere, this blindness for "decentralized" everything as an answer-all. Decentralization only works if ppl act responsibly to make it work. Otherwise, it fails. Economic incentives also work to force ppl to do something, like how POW is done that keeps the integrity of the network because of the investment to do so. Not allowing disintregrity and alteration of the chain is in one's best interest.

There are no rules other than code=law stupidity to allow anything here. Code can't handle all of human behavior. It's code... lol.
