Do crypto leaders believe in sanctions? How do they apply for crypto if so?

Take the Russian attack in Ukraine for example.
- Should sanctions be able to exist?
- If so, should sanctions exist for crypto? For example, should sanctions be able to prevent exchanges from operating with Russia or operating with certain wallets?
If no to both, what methods do you suggest to impact the impact of war or geopolitics?
