Really? My experience has always been that the AI values my last resource as any other resource, but values its own last resource very highly. Either way, I'd say my overarching point of East India <<<< Bazaar still stands since some people were drawing or asking about that comparison. Since with a Bazaar in that same situation you wouldn't be trading away your last copy in the first place.
You forget that East India is available from the start of the game. That alone makes it better than Bazaars.
In the early game, you can either sell more luxuries than other civs and get huge amounts of cash or trade for even more happiness than usual, expand like crazy and have easy access to the "we love the king" days (+25% growth in that city!!!).
As soon as bazaars are available, they are better of course, but that's only compared to Arabia. Overall, the dutch ability remains very useful throughout the game and again, it has the potential to guarantee you a huge kick-start.
