learn Esperanto. The problem is that it takes up much more space than English
That’s not how Esperanto works—it is not a philosophical language. While in theory it is 100% agglutinative, it is not used in that way, and the wordbuilding affixes serve more like a mnemotechnical device when learning the language (and it is very cleverly designed and very helpful).
As for the size, Esperanto is not longer or shorter than any particular other language—it is English that is somewhat shorter than the others, due to many mono- and disyllabic words. Also consider the fact that translations are usually longer than originals.
