No its not the same thing because bitcoin doesn't contain personal info. The difference here is If someone makes a post about you on steemit and it can't be removed it breaks Eurpoean privacy laws.

The Bitcoin blockchain contains plenty of personal info, especially if you consider the transaction data to be personal info. And I could go copy the text of your intro post for example into the Bitcoin chain if I wanted to (and paid for it). Would the Bitcoin blockchain then be illegal in Europe?
