I don't presume to know the needs of Montanans. My state is diverse enough that statewide zoning laws are obviously specifically crafted with a certain subset of the state in mind and are unworkable for different communities.

For instance, there are laws that prevent certain stores (alcohol sales, for example) from being within X miles of a school. There are cities where the central location where the central location of the town where all commerce happens and where the school is is less than a square mile.

Unless you're proposing legislating the removal or limiting of zoning on the federal level, it seems like an incredibly bad idea.
