I first thought this was for testing farming in space/Mars. But yes, in reality it's for tax reason. And it doesn't make sense to let all that land go unused.

Interestingly I know a family that 'farms' on Maui so they can live on a land that's zoned for farming. Supposedly the land is zoned for farming, so they bought the land, built nice houses and also farm to satisfy the requirement for zoning. But of course they are not farmers...
