I don't like any of the options.
I don't see the point of the last one. It's a truism for most authors. Should strangers dictate author's wages? Most of the people who buy your books will be strangers, so the point is beyond debate.
I have better questions:
If a title is not available to buy in electronic form, and you download it; is it stealing? Would your position change if you own a paper copy?
What if the title is not available in any form (paper or electronic)? Is it still stealing? If so, how would you propose that it be paid for?
