Don't need DNS. Access any node by IP and get a list of IPs of peers.
Shutting down the internet is ideal. But authoritarians like Chicomms want the internet up and the ability to honeypot, entrap, bribe, etc that comes along with it. Our own deep state wants the same. Even our shallow state tax authorities want blockchain access so they can trace all transations to the greatest extent possible.

Watching and tracking everything is a given. The question was whether Bitcoin activity can be blocked. The answer is they can't (other than shutting down the internet for 100% of the population) and don't need to as long as they can track everything.
Track the routes and poison the IP tables. Easy when you have direct control over the ISP backbones due to "National Emergency"...
