"Incorporation" of any fundamental human right is never a bad thing.
The Fed is not "forcing" states to relinquish any power they have. States do not have the right or power to deny human beings of fundamental, unalienable rights. The concept of "incorporation" simply means that there is now a legal construct that prohibits States from doing something they have no right to do in the first place.
Just like states do not have a right to establish religion, or control the press, or regulate free speech, or search you without a warrant, or detain you without cause, they do not have the legal or moral standing to control, restrict, or regulate a right that shall not be infringed, such as the right to keep and bear arms.
That's what "incorporation" really means...
