It's a sacrifice in the same sense that running the DMV or building a bridge is a sacrifice. But, most countries have no trouble organizing that kind of sacrifice. We have had public works, bureaucracy and infrastructure spending for thousands of years. In most cases it means taking a small amount from many people. But, willfully reducing economic growth worldwide? To say to an individual "You, personally, could improve your material circumstances with this land, but we won't let you"? That's a sacrifice, and a game theory problem. Even if both goals are equally worthy, the latter type of situation will be far harder to co-ordinate than the former.
