So here is an interesting copyright question to ponder: are we allowed to redistribute binaries of open source software that have been compiled and signed by Apple?

Recovery mode on Apple Silicon will only run Apple-Signed binaries, but that includes any random thing from macOS. You can just run /usr/bin/python from a macOS partition. But what if I want to use python without having a full macOS installed? Can I just redistribute those?

Effectively: does merely compiling (without making any changes vs. published, freely-licensed open source code) an application create a derivative work? My understanding is no, because there is no originality involved in the process, it is purely mechanical.

you can't create this binary with only the sources though, you also need a code signing certificate which is not covered by an open source license

You can create the *binary* (as in the text section) with only the sources; only the binary code as in the processor opcodes and data is covered by copyright. Digital signatures and keys are not copyrightable AIUI.
