In answer to the original question about "what would it be worth to me"...
The larger the scale of the community the more attractive it would be.
A one block neighborhood of shooters in a suburban area: I would favor that if I was planning to live on that side of town due to office location, etc. But I wouldn't move to another city for it, or move 20 miles across town. Probably half my neighbors are at least armed where I live already.
"Gunpark"
Now we're talking. a handy range, probably an onsite gunsmith, a few gun shops, easy FFL transfers and private sales, several collectors, oddles of reloading setups, etc. I would seriously consider moving to be in such a place. Especially if it was within a couple of hours commute of where I work it would be close to a no brainer. My wife would chukle but would indulge me on this.
Guncity, USA
Wow, now I might be willing to consider a job change or whatever it would take to move there. Open carry and concealed carry encouraged. Multiple ranges and gunpark communities. Maybe even able to elect a state level representative, but at least all local elected officials would be shooters as well. Maybe even a Wal-Mart that sells a variety of handguns
This would start attracting a lot of gun oriented businesses: importers, manufacturers, custom smiths, MAJOR lead receiving depot or smelter
, outfitters, and even destination attractions (machine gun shoots every month, competitions, shooting academies, etc.).
Guncity would even be large enough to have its own golf communities, airparks, etc. the trick would be to maintain the integrity of the shooting friendly community over time. I have seen it happen over and over again in organizations (private schools, youth groups) where newcomers that don't fully share the founders' values begin to get into positions of voting and decision making and pretty soon the organization has drifted from a tight focus to almost anything goes in the name of diversity and tolerance. But, hey, it would be a lot of FUN however long it lasted.
