This is because Go bundles a big runtime in every binary.

Is there a way to not do that?

You can also write allocation free Go, by computing everything on the stack. (Use pprof tool to analyze your code's allocations)

If you want smaller binaries without a runtime or GC bundled, you can try out tinygo [1]
