sorry dumb question (i think that answer is yes): can i use this to build a statically linked binary of my kotlin app?

You can use Kotlin Native to do that — if your app doesn't depend on anything JVM-specific (apart from the small subset of basic things reimplemented in Native), of course.

You can use SubstrateVM to do that for free, if you don't use too much dynamic coding.
