Anything done using software is only “significantly harder” today… your argument is nonsense. Someone will build an easy way to view and decode data stored elsewhere and then what? Legally you are hosting the blockchain, you neither uploaded the content nor do you know what content has been encoded to the chain. The chain can’t show you pictures it requires external software to do that. There is no legal justification for prosecuting a node operator. Any country that does persecute a node operator is not free and should be resisted with force.
