Gender roles aren't important to society. By enforcing gender roles, you are just trapping people inside a box in which they do not feel trapped. No gender roles does not mean that they will be reversed - women can still care for children and men can still go to work, if they WANT to. The absence of gender roles would be beneficial to society, if anything. People would be allowed to be free and do as they wish, without limitation placed on them. People who feel comfortable in the traditional gender roles can still follow themif they wish, but people who don't shouldn't be expected to. What really matters is what is on the inside, after all, not our sex.
