Are there "Identical Twin" plants?

This stupid question started such a huge argument? Of course asexually
reproduced plants are genetically identical! I learned that in grade school.
What was the point of this discussion? Really. I don't think people should
be concerned so much with max growth limits of plants, we should be more
concerned with the max growth limit of the human population. Of course
that's off topic. If this concerns feeding the planet, then genetic
diversity is more important than mass cloned crops. You can only grow
certain potatoes varieties in certain "environmental" conditions. Duh.
Another thing, if something was somehow given "unlimited" growth, wouldn't
that come at the expense of other organisms? Wouldn't the potatoes take
