As long as the farmer can still produce for himself and his customers then this is good. I'm sceptical because local governments in the United States and in particular my Commonwealth of Virginia, are incentivized by the federal government grants to impose wetlands acts on small business and property owners. Meanwhile the federal government has huge shipyards, military bases, airports, and military weapon depots that take up billions of hectares of marsh and wetlands.

If the farmer can manage his own land the way he wants them it is good.
