Good that at least one of you likes my idea of abandoning Berlin, thanks Optional! 
But in fact: it would have been a very strong strategem in this particular game. (And if you look at the games of the top GOTM players, you will notice that they do it all the time.)
I know we shouldn't look back, but there's one more thing I need to say, because I hope it will be instructive: one key ability for Civ (or other strategy games like Chess) is to remain flexible as long as possible. Consider all possibilities and keep prepared for all of them. Burn the bridges behind you only when absolutely necessary. Then you retain the ability to react to changed circumstances. (I guess, this is what the Overseer dubbed so nicely as "herding cats"...
If you read this thread, you'll notice that I've changed my mind about certain things several times, whenever new information or new ideas came up.)
Anyway, in our case: by building the GLib now, we lost a lot of flexibility without necessity, because as I already wrote in one of the earlier posts, we have exactly one contact at the moment, and the GLib requires at least two. So there wasn't any need yet to build the GLib immediately. Suppose now that in the next 5-10 turns we find out that we are on a huge continent alone with the Dutch (they could as well have popped their tech from a hut instead of trading it from someone...) So the GLib would be useless for a long time to come and we would get much more benefit from the Pyramids. But then it's to late to switch strategies, because we have already used up our leader!
I'm not saying this is likely to happen, but still I would have liked to keep flexible and keep that option open for as long as possible! (And in my opinion the discussion of whether we can get the Pyramids and the GLib was far from decided, yet.) Now getting the Pyramids will be impossible.
Regarding the reload: I agree with the Overseer here. Done is done, no reloads. Anyway, here is a little anecdote as "comfort" for gamezrule: in one of my GOTMs a while back I was playing for 20K (where you want as many wonders as you can get). I got an MGL (which can rush wonders in PTW/Vanilla) and moved it to my capital. I waited until the current wonder was finished (it had already a couple hundred shields in the box, so didn't want to waste the MGL on that), switched to the next wonder, selected the leader --- and absentmindedly pressed the "Build Army" button...
(These two buttons look so similar, don't they
) Of course no reloading allowed.
So you see, gamezrule, I have done things even more stupid than rushing a wonder in the wrong town...
And again: don't take criticism personally. As Overseer said, the purpose of this game is to give us all the opportunity to gain experience and learn something new. And how can one learn better than from mistakes
