does it apply to blockchains? has there been cases where a handful of validators for forced to delete blocks for obscure chains?
does it apply to people standing around when you yell out something? can you go up to them and force them to forget the sound vibrations you sent out?
First example is indeed a good one. But do we send out messages (notes)?
Second one less, I think, because that would not be in digital form, right? And lets say they use a device for that digitalizing everything and keeping a record. If that would be the case, especially if a company does it, then yes I humbly think.
