Seems fair to me too. I have done and continue to do this. I have no ethical qualms doing so. Should I?

I don’t. I just don’t want physical books. I don’t have the space to store them. And the kindle is far more portable.

You can throw the physical book away or recycle it as paper. Buying them is just to make payments for the pirated books.

Please don’t do this. At least donate to your local library or thrift store.
