so does this mean that (for example) the olympics can require quad9 to stop resolving youtube because someone uploads a video to youtube that is a copyright infringement? what stops a malicious actor from claiming copyright infringement and causing sites like youtube, netflix, and hulu to be taken offline entirely while it's worked out?

Presumably YouTube would be able to intervene to convince the court that this is a disproportionate response, given that YouTube already has a system in place for copyright holders to request individual videos to be taken down. Whether this defence against collateral damage is, on balance, good for web users is a more complicated strategic question.

Playing devils advocate, there already is a system in place for copyright holders to request that any website is taken down that obviates the need for any DNS level blocking (ISP level blocking).
