> you'd probably be a bit annoyed if others just stole the product

For sure, no one is arguing for stealing fruits here. However while you can steal physical fruits, you cannot steal genes.

> then why should it be available for everyone?

Why should it not be? You seem to view the right to breed a variety of some species that you created as some natural right and default. It is not. What you are arguing for here is the state going after people for creating the environment for plants to reproduce, which is a natural right.

The basic purpose of patents is to make it worthwhile to develop something new and valuable. They are unnatural - but useful. Working backwards, if we want people to spend time and money developing new breeds of plants, you arrive at these kinds of rules.

>you cannot steal genes.

Why not? You can steal bits, unless you think copyright law's bunk as well. You can even steal ideas (patents).

[basilikum]

You can steal neither of those. You can copy them and in some specific cases copying bits or letters or some other human creative work might be unethical, in a lot more cases it can be illegal, but it is not theft.
