The average user won't start using Bitcoin just because you said "hey, come on, I made some space just for you!".
If they didn't come yet, it's not increasing by only 1MB that will convince people to use. The mass adoption won't happen so soon.
Indeed, they will not. But on the other side, as long as this question remains unsolved, bitcoin appears very unstable from the outside, and this is prohibiting people from starting to use it.
