I think that if you enter Amazon page in the part where you change the settings of your kindle, and you just change there the country where you are located, they will allow you to buy. Try it and tell us.
But it really is worth buying paper version. Of course it depends on how much you like the subject in question. If you like the blog enough, buy it. I am in Brazil and I also pay more for shipping costs than for book costs. I buy very few books these days. The only issue I have with buying Jacob's book is that there isn't a hardcover version.
At first I thought you could be having some problem with censorship or the like, hence avoiding the paper version. If this is not the case, go for it!
