for people who love the littlest dairy goats
It's really not a good idea. You will have doelings getting pregnant way too early and could wind up needing c-sections. Your senior does would wind up getting pregnant way too often, which would not be good for their health because pregnancy is a big drain on them, and they need a few months to recover and put weight back on. Good milk producers can get really underweight by two months after the kids are born. Also, you won't be getting much milk if the does are pregnant all of the time.
Plus, your milk will probably be stinky because the bucks like to rub on the does.
Most people have at least two bucks anyway so that they can keep daughters and breed them to an unrelated buck -- or at least not their father. If you have two or more bucks, you can keep them in their own pen, far from the does so that you don't wind up with any accidental breedings.
Can a buck be tethered on a long enough line?
