Sure. You can have market power in the antitrust sense without being a legal monopoly.
I don't know where you work, but I'm personally loving the Annapolis area. (As I like to say, VA won't let you have weed, DC won't let you have guns, but MD will let you have both.) I also have two fiber providers to my house, and the state is building municipal fiber in the more rural counties that don't have FiOS.
Ahhhh Annapolis... Home to a big naval academy & supporting infrastructure/economy. That sounds great. My hope is to find a sweet/similar deal somewhere between Laurel & Crystal City.
If your view of the Second Amendment runs more towards militias than self defense, MD isn't bad. For long guns, there is no permit required, and either concealed or open carry is allowed without a permit. The ban on "assault style" weapons just means the state police runs a website listing all the semi-auto rifles you can legally buy (which is a lot). You can get your 30-round magazines in Virginia and bring them in with no trouble.
For long guns (which is kind of pointless, I suppose). The point is that there is nothing preventing you from stocking up on arms for when MD/DE/PA have to become their own country.
You’ll need to shoot for constitutional carry. Here in KS (least gun laws in the nation) there is statewide open & concealed carry, no license required, at schools, bars, university. Though there would be a trespassing charge if you refuse to leave if asked. Still need a CCH license to get around federal Gun Free School Zones. No NICS if you have CCW.
The recent Firearms Protection Act says firearms and accessories (suppressors) made in KS are exempt from federal regulation. Though a couple of guys lost their federal case when they built a suppressor and sold it; at least no prison sentence.
