only a tiny fraction of the people will bother with the immense overhead of steganography
it would much more practicable to resort to alternative channels outside the internet, like mesh networking using direct comms (typically ad-hoc wifi modes and other radio protocols to avoid the liability/detectability of cabling), sneakernet, IP over Avian Carriers - those are all cumbersome and rather slow typically, but still orders of magnitude better than trying to pass stuff over ISPs using steganography
