I don't mind this secondhand marketplace if the following happens:

1. Rights holders have an "opt-out" option.
2. DRM Free ebooks are not included in this secondhand marketplace. Because DRM Free ebooks can technically be copied an infinite number of times, I would hate to see my DRM free ebooks in this type of marketplace. And selling (or giving away) copies would be a violation of my copyrights.

Otherwise, I don't have a problem. I do like that the original owner would lose access to the ebook and could trade the ebook only a limited number of times. But I do wonder how this type of marketplace would impact income for authors.

I agree with everything here. My feelings exactly.
