Yes, the sum of all users are the community, not the mods themselves. Therefore if the community is truly aligned in a consensus to not reopen a sub, it won't matter if the sub is forcibly reopened by a newly installed moderator because the community, the users, won't come back anyway. So there's really nothing to complain about; the community is now dead or moved off reddit and it doesn't matter what reddit does with the subreddit that formerly hosted that community.
Unless of course the community is not nearly so united as claimed. Then maybe most of the community will come back to the subreddit. I think this is probably this is what will happen in most cases. And this is why people are mad about reddit threatening to reopen subreddits; because they don't actually have a community consensus to stop using that subreddit. They rely on the subreddit being locked to force the community's hand, and as soon as that leverage is taken away the community will be free to make a decision which is contrary to their own desires.
