Ok, so I have this weird headcannon where there are so many supers in paragon/the isles because they're required to be there so that the rest of the country (world?) doesn't have to deal with this BS. That's why the walls and shields. That's why you can't just fly out of town. It's a giant Truman Show situation.
This would just amplify the effect in my headcanon. The whole area is a themepark as far as the rest of the country is concerned.
As for my advice: Leave, if you can. If you can't, see about getting some gear, just in case. Armor, a weapon, a saferoom, anything to help. This place it crazy.
