I don't see how you can get around this, unless you're going to ask people to sign some kind of moral code that they're not going to abuse a program that's there, in order to make it more accessible to young entrants. As with any of what's going on, it's based on trust. And it would have to be based on trust going onward as well, with something like that.
There are programs. We have the new entry program here in Nova Scotia. It's interest relief, and it's not very much. But you could do the same thing. You could increase your price by the amount that you know a young farmer is going to get for it, and you would just have to hope that people aren't going to be that low.
