Yes, and because of that the FSI report can't be considered the ideal reference to answer OP's question properly, as he mentions things such as native American languages and language isolates as possibilities. English speakers who try to learn much more uncommon languages, such as ǃXóõ and ǂHõã for example, with an incredible vast number of speech sounds, idiosyncratic grammar and virtually no learning or reference materials, are usually only linguists doing some kind of research, and even the materials they have written are hard to find and not enough to learn much.
Then, to learn these isolated languages to a basic level, people often have to live where others speak them (maybe bringing them to their homes would work too, but I'm not sure how that would work out), places that are often very poor, underdeveloped and uncomfortable to be in for someone from a richer place. Also, it's necessary to find natives who have the patience to deal with an adult who can't communicate using the right words for years, who very likely will never be able to pronunce them properly, and a strong determination to overcome the frustration that comes from that inability. In addition, they can't use the language for any type of 'useful' communication outside those places, because the small number of natives who know them mostly don't have access to any type of modern communication technologies such as telephones or the Internet, and there are no recorded movies, music, literature or anything like that to be entertained with the language and reminded of it - unless, sure, they record something while in there and find a way to transcribe what's being said.
This peculiar social aspect, and the constant reminder that all the time spent learning the language will be for nothing (again, unless they work with the language somehow, such as linguists) adds much to the difficulty of learning them, often as much as the absolute aspects such as phonetics and grammar.
