Of course there are.

Don't throw the hardware away, and fly a lot.

Reusability involves weight and cost penalties.

Flying a lot creates a chicken-and-egg problem.

But I do see on the Astronautix site the sad story of one attempt that
could well have been successful.

If you can't fly a lot, just build your rocket out of a lot of identical
units!

Despite clearly not being optimal in terms of overhead mass, OTRAG
apparently already demonstrated how one can significantly reduce the
costs of launching rockets into space.
