You're acting like a social network is a web site. It's not, it's a fabric. If you want to be able to do this type of editing, fine, put up a web page, but don't try to pretend that you posting something that makes you look like an asshole, and then me commenting on it, calling you out for being an asshole, and then you changing the original posting so that it looks like I'm the asshole for engaging in an ad hominim attack, is somehow OK.
I'm not sure how this relates to anything, or how "put up a webpage" makes any sense at all (every social media site I've heard of uses a webpage of sorts..)
You're being disingenuous, or intentionally obtuse. You putting up your own web page so people can see your rants is a far cry from some putative distributed Facebook competitor that exists only to get out from under the "heel" of what the OP dislikes as properties of Facebook he wants to make as architecturally difficult as possible to implement.
There's nothing about "social media" that says "permanence." Snapchat for example does the exact opposite of permanence and automatically deletes things for you.
No, that's a feature of snapchat in particular which is considered by most people to be a means of evading law enforcement, at worst, and the same thing as having an expiration date where the service effectively has a sliding "we're going out of business, sorry" at best. Think MySpace.
Ephemeral is a feature to only a very few.
It still falls under the label "social media" though.
That more of a consequence of the inability of the journalists to classify it, and so they pick a lexicographically "a cherry is like a tomato, because both are red and fruit" close thing, and call it that. IT also sells itself as that, because if you can sell yourself as that, you can pretty much get VC funding.
I can't just erase our shared context from my memory, if I decide Bob is a Nazi after the fact.
No, but you can go ahead and not tell all your friends that Bob's a great guy and cut him out of your life. I'm not sure how any of that has anything to do with any specific communication tool though. The internet does not work like a human brain, for better or worse.
Am I just supposed to "de-friend" everyone?
Or you could just you know, put Bob himself specifically on ignore or whatever equivalent exists. Sure he might still show up in your friends-of-friends lists but he shouldn't be able to shower your wall with hate speech (though again, you should really be questioning your associations if your "real" friends are perfectly OK with Bob's rants.)
I think I pretty much want to out Bob as a Nazi everywhere. I want to punish him for being a Nazi by ensuring he is socially ostracized to the point that he gives up being a Nazi because he's decided that his perceived costs outweigh his perceived benefit. It'd also be nice if he can't pass on his heinous meme to another unsuspecting person by being sly about slowly indoctrinating them, and it'd be nice if any woman who might get into a relationship with him and have his kids would be able to make that decision on the basis of complete information. People frequently make an emotional or financial investment in a bad venture, and then rather than cut their losses, they "throw good money after bad".
This is how gambling addiction works. It why people stay in abusive relationships.
By allowing the rewrite of history (discussed earlier), you remove the need for the social lubricants of politeness, civility, and (possibly pretend) rationality, which are required in real-world interactions.
Except this is explicitly a network of "friends." If you don't like someone, don't friend them.
You are either an old anarchist, or you are otherwise not very knowledgable about how younger people view "friends" on Facebook. Calling them "friends" is a terminology Facebook uses; these are not "friends" in terms of "web of trust". This is not like a PGP key-signing party.
Younger users accept *all* friend requests. If it turns out they don't like what the person is saying or doing, they "unfriend" them later. But the default is to accept *all* requests. This is not how older people do it, and it's not how you would expect them to treat an online relationship, but it's how it works.

That solves the troll problem in all but the worst cases (which would be the equivalent of a real-world stalker.) And even then, the worst they could do would be spam you with friend requests which you could ignore.
In fact its intrinsically not a part of the medium. Social media is about communication, not about history.
I think you haven't been following the whole GamerGate sock puppet situation very closely. Yes, it's the equivalent of real-world stalking, and there's no mechanism to deal with trolls now. In a distributed social network, you could be scrupulously upstanding with your immediate peer nodes, and be a total asshole otherwise. Once you are inside the web of trust, you're inside, and even if someone wants to not hear from you, as a peer node, your node doesn't have to run unadulterated software; it can imply graph relationships that don't exist outside their rogue node.
This is, in fact, precisely how the TOR network had been infiltrated by various third parties: peer-of-peer implied trust relationships.
I don't think this is a workable concept, unless you can figure out a way to (1) Stop the whole GamerGate thing in its traces, without hugely invasive surveillance to root out bad actors at their houses, and figure a way to cut out the cancers permanently and/or take criminal and/or civil action to force them to not be bad actors ("Bob is a Nazi; let's put social pressure on him to change that"/"Bob is a criminal; lets put social pressure on him to not act that way by locking him in a cell"), and (2) Figure out a way to do source verification so that if ted trusts Bob, and Alice trusts Ted, that Alice can legitimately not trust Bob without having to throw away the trust relationship with Ted.
