I, and the rest of the Internet community, would like to invite you to start a
router company and show us how it can be done with far less memory.


More seriously, you might take a look around and note that there are not a
great deal of difference in the amount of memory needed to support a prefix
across the various well-known implementations.  Which is not to say that we're
blameless, just that a lot of good people have worked hard and are all equally
incompetent at conserving memory while simultaneously producing a scalable,
stable, feature-rich implementation.
