The alternative is that the ecosystem itself is written in Clojure (or at least the most important parts of it).
Of course, you will always have a set of points at which the language needs to call lower-level functionality, but you should keep that set as small as possible, to make the ecosystem easier to port.
And in the modern "client/server" world, you really need this, because systems are often heterogeneous, and you often need to move one piece of code to another part of the system which runs on a different runtime.
