I'm very suspicious of this claim. If I and seven other own a piece of property, I alone cannot sell it to a prospective buyer. The same would hold of copyright. Although each owner has a copyright, a single owner cannot grant away the entire right to a third party.

To "sell it to a prospective buyer" would be equivalent to the grant of an exclusive license. To "grant an easement on the property" would be closer to the grant of a nonexclusive license. However, the analogy fails to some extent, because it's not physically possible for multiple people to enjoy the entirety of physical property simultaneously in the same way that this is possible for intellectual property.
