It isn't our calling as Christians to write laws that force people to live moral lives. As much as our communities might need it, and as bad as things are, imposing our morality on others isn't the answer.
It doesn't work. People may be forced to give up alcohol, but they are still going to hell. That's our calling - to bring people to Christ - not to force them to behave the way we want them to or to solve all their external problems.
