Well sure the the obscene yields do help destroy suburbs, but another reason they exist is to ensure military targets are hit. ICBMs used to be inaccurate by a couple miles, so increasing the blast radius ensured that didn't matter. Now, ICBMs are more accurate and the world generally fields less powerful bombs.
oh you widened your city 50 miles? i'll just stuff a few extra warheads in this here missile and make sure i saturate the whole thing 🥰
