Sorry, not sure what the answer is. Steemit Policy is written to protect itself from the legal system in the United States. It is the laws they have to operate under. I know they added in language specific to the EU laws for people, but not sure if say England told steemit owners they need this person name and phone number that they would have to provide it. They are operating under US law, have no offices I am aware of in the EU, and steemit sales nothing, all they do is provide a space for people to say things.
Sure the countries can block steemit web sites, but they can not block the blockchain. So there will be options to get on the blockchain. At least I do not think they can block the block chain.
It would have to be some pretty fantastic technology to block an entire blockchain I'd imagine. So it seems there's just an open chasm of grey areas we have to work with! This is hardly un common (e.g. Fair Use) but still frustrating =/
