I suppose I can agree with your points here. I just have a different opinion about "not being able to join the Enclave". It wouldn't piss me off at all if you could have the option to join the Enclave, in fact the lack of the option is the main flaw with Fallout 3 that I see. It seems to me that if you had the option to join them, the "Enclave death= explosion fest (which I agree was freaking ridiculous) would have been prevented or at least helped because you would have seen the battle from the Enclave's perspective. It seems to me that the option was cleary thrown open with President Eden's asking you to aid him and they should have expanded on that. It would have allowed people to see the true side of the Enclave and why they do the things they do without showing them in an "OMG BAD GUYZZ" fashion. I say screw that fact that the LW is technically a vault dweller. If it gives people a good view of the Enclave and portrays them as being more than just a "shoot-um up" faction than I say go for it. I think there needs to be an option to help the Enclave in more ways than what we saw in NV (although they did a good job with that) if we are ever going to be able to see the Enclave as more than just the "baddies".
I think a lot of people would all like to live in a utopian world were the Enclave were humanised and not completely butchered but it really depends on your perspective, I would sooner the Enclave die than start accepting wastelanders, any Enclave that would do stuff like that would not be popular with me.

I also don't think bringing them back was a bad idea. Heck if that hadn't happened than the Enclave might have faded from Fallout memory. Instead they were given a "last stand" and brought out for the rest of the gaming community to see. Had the events of Fallout 3 not happened (i.e. the inclusion of the Enclave), there would not be nearly as many people supporting the Enclave as we see now. (Ex: I see random American patriotic songs on youtube which have nothing to do with Fallout 3 with high-rated comments such as "Its the Enclave!")
Well as good as it might be that some people got into them, canonically they are [censored], dead pretty much now, all because of Fallout 3, they were killed off in an explosion fest which they did not deserve.
Finally, (and this is just my opinon) Fallout 3's "death of the Enclave" actually seems at least a bit more logical than Fallout 2, I mean in Fallout 2 the Enclave's top secret base, the President, the battle-hardened secret service agent, and most of the Enclave's forces in the Rig were brought down by a single villager from a tribe. Not bashing on Fallout 2 here, but at least in Fallout 3 the brotherhood was backing the LW up so it made it a bit more plausible.
Well Fallout 2 had it's flaws, like how did nobody notice the Oil Rig dock, it was purposefully impounded to prevent it from being used to reach them.
