Why don’t we have over-ocean cables to ferry cargo/cargo ships?

Cable would get too heavy to hold up by both ends

Cable ferries exist, but the longest cable ferry route is 2 km [1]. Ignoring material science conerns, energy efficiency concerns, and the difficulties they add for other navigation, cable ferries tend to be quite slow even compared to intercontinental shipping, have a single vessel per route and have a two point route.
