I disagree. 3D is art, and there's value in uniqueness. For example, game characters have to be always unique. Of course there's certain props which could be reused, but I don't think the market for 3D models is that huge. 3D models for printing purposes is a different story. Another problem is that those 3D models could be ripped fairly easily (they are downloaded in your browser anyway). That would put away any serious sellers. Although, reusing stolen assets in games for example would be noticed. Of course, as a complementary monetization strategy, it wouldn't hurt to offer downloading with paid rights for reuse. As a learning 3D artist myself, I think this is a really great way to show off your 3D and explore what others have done.
