The article misses a lot, it assumes the only battleship on battleship combat was Jutland. That's simply not true. Surigao Strait[1] and the Naval Battle of Guadalcanal[2] both definitely occurred. As did Hood/Bismarck (this one depends on if you consider HMS Hood a "Battlecruiser" or "Fast Battleship" IMO it's the latter).

But the point of a battleship wasn't just showing off, it was also area denial. You really can't move another surface combatant into an area with a battleship unless it is a battleship (that didn't stop Taffy 3 [3] from trying). So battleships served two clear roles IMO: Area denial and shore bombardment. There is a reason the US Navy kept the Iowas around until the 90s. For what they do there is nothing like them. That said let's also be clear the counter to a battleship is an aircraft carrier, not a battleship based on existing data.
