TFTNT, oh can you add me to the list

I see the whole magic thing one of two ways:
1.) Magic Comes With a Price
That being said maybe when Gold used magic on the shawl he had to sacrifice the magic on the outside
2.) The Town Line Theory
In that other than the shawl, most magic doesn't work beyond Storybrooke. It's different with the shawl because that's what the magic was intended to do, cross the boarder
