> every ISBN should have the author's bank account number next to it and obtaining a copy of the ebook should be as simple as sending $X to that bank account, then finding a torrent by ISBN.

which is fine, except what happens if the author sold the rights to another company that then demand a different set of condition?

Or are you saying that the owner of said copyright does not have the right to decide such (for example, they would want to decide that the works is only available as part of something else sold)?
