Internet in hands of the government ?

Seeing Current situation in iran it has come to my observation that shutting down the internet will remove huge chunk of bitcoin users away without connectivity its basically useless.
I mean yes u can use radio broadcasting and there are services for it but as i checked there seems to be either few or high entry infrastructure . I think this is where bitcoin adoption is hurdled on its weak communication connections which can be easily seized to exists by an entitiy ? Im trying to wrap my head around this feel free to correct me .
