I don't think you've known many if you don't know any that want ownership limited to a set number of guns, stored outside the home -- effectively meaning you no longer have a right to arms.
Where Massachusett's laws break down, from my perspective, is in requiring local police approval for licensing. Like all states that require some sort of Firearms Owners ID, the exercise of the right then becomes dependent on the police authorities permission, which means it is effectively a privilege distributed by the police rather than a right exercised by an individual. I don't know if they still do it, but Massachusetts used to require guns to pass a rather arbitrary safety test, that mean the state wouldn't issue permits to purchase any number of classic firearms such as the Colt Peacemaker or the former U.S. Army .45 Automatic.
The point being, of course, that for all its efforts, Massachusetts its not some crime-free Utopia. It ranks 18 out of the 50 states in violent crime statistics (source:
http://www.worldatlas.com/articles/the-most-dangerous-states-in-the-u-s.html) -- meaning that the various complications it imposes don't make it any better in terms of violent crime than a state without all the restrictions, such as Kansas (which ranks 23), nor much better than Texas, which ranks 15 -- and those states don't require a Firearms ID card, etc.
