Cryptocurrency justifiably has a bad rep, given how much profit-motivated hype is attached to it, but it offers an alternative to steganography for resisting government surveillance: fully decentralized platforms that massively increase the cost of enforcing laws against the use of strong encryption.
The public blockchain is the first solution to create a stateful protocol that is fully decentralized and can persist over a long period of time. For a public blockchain to function, it requires a native digital currency that compensates the parties who provide the economically costly digital signal that is used to coordinate the convergence on a shared state.
The blockchain was designed originally to survive state-level attacks. I responded because you brought up both the subject of censorship resistance and cryptocurrency, implying that the two are unrelated, when the former is the latter's raison d'etre.
