The problem is that entry points in the network (exchanges) are censored or will be and you need exchange to actually extract money to spend, living in a authoritarian country. You can argue that people can use pure bitcoins by themselves, without fiat money, but that means that there should be an infrastructure where organizations accept and process btc, and they aren't doing it due to technical limitations of blockchain. It will only function as a "resistance coin" until there are some unaudited exchanges or some freedom in movement to go to other country for your money etc. If/when country will go "full dictatorship" btc won't be able to provide any useful utility.
