government would limit land ownership to citizens, as an extension of the idea of defense of the nation

Yes, I agree with that. As long as there is a credible concrete threat, the government may restrict trade in some specific circumstances. For example, striking a private deal with some Arabs involving weapon sales would be rightly prohibited under the circumstances. Those are temporary wartime restrictions.

I don't see facilitating the government in applying legislation is enough justification though.

Agreed that we could apply restrictions in trade as part of national defense, especially with weapons, and also agreed that we don't want to get carried away, like supporting the mohair industry under that guise.

I see land ownership going beyond that though, perhaps partly because it depends more on government for its protection and definition.

I don't think I understand this sentence. Perhaps you could fill in the blank for me: "...enough justification (for) _____ though."
