What about Namecoin's .bit domains?
They are impossible to seize once claimed by whatever entity, but by rolling back the chain, you technically can make sure X entity has no longer the control over a specific .bit domain. It is however very unlikely that someone is able to roll the chain back with how Namecoin is being merge mined mostly, which means that it accounts for an immense amount of hashpower thanks to Bitcoin.

It's very niche still, and something most average joes don't give a shit about. People want to access websites in an instant, and not by first visiting a proxy site to open .bit domains, or even to install software. No chance. It will only become a viable option when the whole internet has turned into one centralized shithole.
