That’s unfortunate but not terribly surprising.
Humans will build a bar as soon as there are more than two people that want to drink but you typically need much larger populations before you get a sober community at all. You usually only get dedicated sober spaces when those communities get big enough.
Fortunately, as many others on this thread have pointed out, there are many sober options beyond dedicated sober spaces.
The FCC has a lot of regulations on it. From what I remember active jamming within the home is still wildly illegal. Depending on the size of your house/room, a far as at cage wouldn’t be too difficult, especially if you did it during construction. If you’re on a budget and don’t mind looking crazy you can line a closet with tinfoil and connect it to ground.
