Question: Why did Hancock end up having to go to New York to prevent his and Mary's powers from weakening? They had lived in L.A. all that time without it being a problem. Mary new he existed since his drunken heroics were always caught on tape or recorded (YouTube), and Nancy Grace even knew who he was.

Answer: True, Mary knew he existed - but he didn't know about her. It was only after both of them became aware of one another that the mutual attraction set in. Besides this, before they met, Hancock was an alcoholic bum living on the streets, scorned and ridiculed by everyone. When he was in that state, it would be a lot easier for Mary to keep her (possible) attraction to him in check.
