Actually: if your premise is that you're an open access facility, then having arbitrary treatment of different users is a really excellent way of undermining that premise.

For example, as was pointed out elsewhere on this discussion, having blocking controls that tend to create a higher bar for people without home internet access means you're discriminating against groups that can only afford a personal mobile device, or only have internet access at a library, or come from a particular national origin, etc.

If you care about anonymous editing, creating underclasses that cannot have it seems an unlikely way to further your mission. It's effectively a form of red-lining.

I don't understand what your email analogy is getting at, so I'm going to leave that alone.
