The vast majority of the time there is an extra resource somewhere thanks to the Birthday Paradox. In fact the very issue that you lack a resource suggests it is in a greater concentration elsewhere.
I agree that such usually happens. But, it doesn't always, so there exist SOME such problem situations. Diplomatic games have ZERO such problem situations.
Can you clarify as to how the birthday paradox relates?

True, but it goes the other way too. The AI's are quite willing to trade with you no matter how much they hate you but good luck trying to get them to vote you in for secretary general if you have razed their cities.
Surprisingly easy once you know how. Check the victory screen to figure out your opponent, or even gift someone cities to ensure them as your opponent. Declare war on them, and then sign everyone else in against them. They'll vote for you, since they won't vote for a tribe they're at war at. True that might come as costly with a bad reputation, but you only need to do so once, while for building parts you need to get the resource each time you start a new part.
I disagree that cultural conversions come as such a problem. The AI only gets 1 or 2 defenders in a city that converts, and you can rather quickly take it back usually... even on Sid. They also don't happen all that frequently if you focus on one opponent and exterminate them ASAP, even on a Huge map with minimum opponents where the AIs drastically outdo you in culture.

The only thing more you need is a transport ship.
No, you also need a spot to land. That's not always possible, or makes for a task in itself. A transport ship also takes time to move. And you might need an RoP too.

In this case there are many clever ways for the human player to instigate wars for the sole purpose of freeing up spare resources even if he is not able to capture them outright.
Sure, but you might actually have to fight a war until you can make peace for a few turns with a neighbor if you do this. With a diplomatic victory, either that possiblity doesn't exist or you'll have to "fight" a war for a single turn.
I really think you have excellent points about roading up AI resources to trade for them, instigating wars to trade for resources, etc. but most of that seems more along the lines of "how to get resources in a tough situation" than "space vs. diplomatic".
