Well, you can't claim IP rights on the first three letter of the alphabet, so abc-homes.com would not be rightfully yours.

And the speculator (distinct from cybersquatter) would not be trying to "sell it back" to you, because you never had it in the first place.

Having said that, I don't PERSONALLY advocate the form of speculating that you indicate.

But rest assured, if I owned Books.com, I would definitely construct an elaborate site on that domain, and would entertain offers. Should I be tarred and feathered because of it? lol.
