Anyone is allowed to prefer a programming style that suits their aesthetics and habits, and like that one over all others. Aesthetic preferences are a very valid way to choose your programming language — ultimately that's how we all pick our favourite languages — and there's no need to make up universal empirical claims to support our preferences.
There's really no need to assert what is really a conjecture, let alone one that's been examined and has not been verified.
If you believe the conjecture is intrinsically hard to verify, you're conceding that you're only claiming a small effect at best (big effects are typically not hard to verify), and so there's even less justification for continuing to assert it.
It's always going to be cheaper to make things in places where labor costs and environmental responsibility expectations are low.
