Yes, but afaik this system has never been tested. If the system is effective that should be demonstrated by putting it in use. Without a demonstration it seems like cheap talk to me.
It is already tested and working - updates introduced and we either install them or not. Are you suggesting to implement some extreme radical changes and see how people react to it?
Yes, my sense is that there is no real test unless opinion is really divided about an update. How will the system handle real competition between two ideas about the blockchain? If the process for resolving conflict turns out to be extremely dysfunctional and chaotic, then I would like to know that in advance. At this point, I'm not sure whether trusting bitcoin is equivalent to believing that there will never be a divisive conflict among the user base, or if I can trust bitcoin even in the event of such conflict. I would feel a lot better if I knew the system had a proven track record of handling conflict through a transparent process. I don't know this yet and won't take the word of developers at face value.
