The US has the first-sale doctrine. The first sale doctrine doesn't say that the company selling you the good has to enable or help you resell. It just says that they can't prevent you from reselling using legal means (i.e. lawsuits, injunctions, etc).
I don't believe the above is true. The first-sale doctrine is part of US Anti Trust laws. Any effort to shut down second hand markets could be prosecuted under anti trust laws. The whole point of these locks is price fixing.
