all for disposable/recyclable BDBs (Big Dumb Boosters). The Saturn V
put 50 tonnes (metric) on Luna - think how much it could put into LEO...

Not much good as a reliable method for crossing oceans that are
prone to having heavy sea conditions, moderate to large waves
prevent the use of Ekranoplans. Good for inland seas and other
large calm bodies of water, perhaps featureless flat plains too.

Beanstalks are a waaaaaaaay major engineering task, and very
demanding of materials technology, 20,000+ km long stalk with
enough strength to perform the task. Not cheap to build either.

half. Half floats away, the other half falls on you.
Then again, perhaps you could use solid state antigrav to support
