This device isn't even primarily targeted at the US or other developed economies. Its intended for price-sensitive consumers in developing nations where LTE isn't even available.
The GP was asking about the Moto X and why one would pick the cheaper phone. My comment is a reply to that. Yes, in a country that is a decade away from LTE its a good fit. But in the West? Might as well spring for the X or the N5.
In France to take advantage of LTE I'd have to double the price of my subscription. The difference between HSPA+ and LTE is not worth that much for me.
In Austria it's about 4 times the price of a HSPA+ connection. LTE is not expected to get any mass adoption until 2016 or so. I read in Germany they are a bit faster. If you want to sell phones in Europe, LTE is not a relevant technology right now.
