We have already solved this problem, and concrete blocks is not the way to do it.
Water can do the exact same thing, but it flows through pipes and can be moved by pumps, it doesnt “break”, it doesnt require complex moving mechanisms, and it can actually 100% fill a given volume (blocks cannot)
We already do this, right now.
This is the whole “they are trying to re-invent trains again” thing.

Isn’t it good to have other methods. There will be places where water is impractical.
