Yes, geo restrictions are frustrating, immensely so, but I do think the number of books available to me has increased (and the average price decreased). The main difference is that what is unavailable to me (but available to others) is painfully visible.
In the past, I purchased English language books at a few international bookshops, and I was restricted to their selection and had to pay their price. I never thought of it as a restriction, but now I do. And I can still go to these bookshops, but I have grown too lazy to do so. I'd rather get frustrated at all the books available - but not to me.
I think we've become rather spoiled
