If your business can be "stolen" by recreating the code, then I think you need a better moat. We live in an AI age, even if someone doesn't have your code it's probably piss-easy to generate similar functionality.

Being restrictive and paranoid towards your future hires is only going to guarantee that desperate employees work for you. Well-tenured industry veterans aren't even going to sit through the entire interview if you make them sign a non-compete.
