I have been thinking the same thing about magic in this series. I believe that the reason may be similar to what @FTGM says, maybe only some can, such as only certain bloodlines can, so if you come from a family of wizards odds are you can use magic, and if you don't then you most likely can't. I like the theory of Zeref and Celestial magic, since he was the one who created the Eclipse Gate since it was in his book, and the fact that Eclipse is a forbidden spell as stated by Lahar and Doranbolt when they hear about the gate, so its not like the royal family created it or anything. Since Eclipse is a combination of his magic and celestial magic, he must have some connections with it in some way (that or one magic since it connects with all magic), so there might be a story on that. This is a theory (a long shot one) but I wonder if Lucy's mother may have some connections with anything as well. Like I said its a long-shot-less-likely theory but I'd like it since Lucy needs development just like Gray does (who if the Silver/Gray theory is proven accurate will happen in this arc).
