I don't know why you would feel bad about restricting harvest on your land.
And I , for one , would feel privlidged to be invited to your land. If someone you invited doesn't like the rules you set down , they should respectfully decline the offer.
The only way to meet your management goals is to have all parties adhere to the restrictions. They can be changed by you if a special circumstance arrises. (I'm referring to a first time youth or dissabled youth.)
