I know you're well aware the advantages being in a high level guild gives, and no they would not be able to compete just for the sheer lack of goods available to do so. There have already been documented cases of guilds being stolen from players, them having to start over and many just flat out quitting, all the work they put into making that guild as good as it was, gone in an instant.
I'm only continuing this discussion here because I believe it to be academic only, Inno will never do this and only a microscopic portion of the playerbase will ever support it.
