It would have taken a lot of Lunokhod missions true, but most likely it would have been at a much lower cost.
Than a national prestige mission that happened to have some scientific output as part of the package? A manned exploration program that put some effort into reducing costs would also have been much lower cost than Apollo.
How much cost reduction is debatable. A significant part of the payload for a manned mission has to be devoted towards keeping the living cargo....well... living. Apollo wasn't a mision about national prestige... it was simply stark fear. That did get kind of muted after the crash of Luna 15, and space eventually became a cooperative venture between the two powers. The Soviet Union even supplied the flight path of Luna 15 to ensure Apollo would not collide with it. That itself is places the Soviet Union as a corrobative witness to the moonflight.
