Or more likely, in partnership with other big tech with similar concerns, they develop an infrastructure that permits blocking/revoking/overriding specific domains, that most clients would refer to in preference to the blockchain. This would be fairly easy to justify on grounds of security and crime.
Or they just don't support the blockchain stuff in the first place, because the current system mostly works and provides a legal process for disputes which they are content with.
This is a given, it's strictly hypothetical.

Luckily we already have something similar to fall back on already, that's a time saver!
E: Honest question, comes off as snark a little - would they be able to just take it somehow or would they need to use jailtime and or broken kneecaps to get it off you? Either way the blockchain's concept of ownership seems like it would be broken easily by law and companies with lots of money
