Then we should have countermining as well since there should be a way to... well... counter it.

Another  option could be undermining. It was used by the more technologically advanced civilizations too. Probably easier to do than ladders (just a guy with a pickaxe).

Ladders are a common early siege method. It may be a good way to compensate for erm... less complex civs in case siege tower has a prominant role for others.
