The problem is the choices you are giving aren't realistic. You are offering: rush a library and tech Irrigation which isn't absolutely horrible to do, but somewhat wasteful or slow-build a settler when you already have three cities, one on dye, which is a pretty bad thing to do actually. I could say "so now you can rush a harbor or sell all your units, declare war on the AI and give all your gold to the AI in the peace deal" but that wouldn't prove that harbors are good.
If you want to sell me on a library for fast knights or catapults, I might be inclined to agree. What I would do in the case you've offered totally depends on where my enemy is and what he's doing. If he's close, I want legions and I'm not even thinking about a library. A library would be a very bad move. If he's distant, it still depends on the intel I have. A library might or might not be a good call. In any case, I'm definitely going to tech either CoL or something to kill him with, not Irrigation.
The question here is really one of foundation play vs. endgame strategy. If I'm building a foundation for a mighty empire, then one little library and +4 pop for the cost of 100 beakers (!!!) is pretty meager. But if I'm pursuing my actual endgame strategy, like a knight rush or whatever, then getting there in close to half the time could be worth it.
But still not if I don't have a lot of gold. 20 gold is no enough to build a rush. The first knight army is 50 hammers (since Feudalism comes with a free knight) and the 2nd one is 75. Maybe I can bank hammers on three trees for 10 or so turns to gain 60 hammers, but I also probably need a barracks which is 40. So we're looking at 105 hammers which is 210 gold in ancient or 315 in medieval. If you didn't have decent savings from the initial gold rush, then it's just going to take too long to deploy your knights. Your roadblock won't be that you can't tech fast enough. It will be that you can't produce enough units to make a proper impact.
By the same token, you could also compare going for CoL quickly. Obviously a library gets you there faster but again if you only have 20 gold remaining, you aren't going to expand much. Having 100 gold left over would mean that it takes a bit longer to get to CoL (perhaps 10 turns instead of 6), but you'd be able to get two settlers out almost immediately.
