You can get "moonshine" at most liquor stores these days, there are a variety of brands available. I've had both the home made and commercial versions and wasn't really crazy about either to be honest. Neither were particularly strong relative to your standard bottle of booze. However, with regards to the home made stuff, that could have simply been a result of them diluting it to a safe enough level to drink when bottling it. I'm not saying all home made moonshine isn't strong, it can certainly be made so, I just personally haven't had any.
Regular commercially available liquor at 80 or 100 proof is plenty strong, I don't really see the appeal of trying to find something stronger to drink.
My grandparents used to make their own wine when I was younger, aka "dago red", which was usually a bit stronger than your typical bottled wine, but again, much of that is a lot of folklore and embellishment. They didn't make their own wine because of some love of wine making, they did it to save money (they lived middle-lower class).
