There is no way that the government will shutdown the internet because if they do that, the people will got mad and there will be a big protest and people will against the government. The government will collapse
internet nowadays are part of people primary needs , just like clothes, eat and any other primary things. could you imagine what happened when government decide to ban people to eat? to wear clothes? , it's same thing when op throw his thoughts about shutting down internet , it's a strange thought lol.
Yes, I believe yes the internet now is an essential part of the life such as food clothes and shelter. The internet is playing a high role in running almost all the activities of daily life, for example if you want to deposit some balance into your bank account you need the internet for it or making a police complain is online, if you want some rescue services you can use both the phone and the online application and also most of the government departments are linked with the internet so there is no such option with the government to shutdown internet.
bigger things would happened if internet access disappeared, banned or something like that. the thought are too far away , governments wouldn't get any good benefit by doing that , it's just make the situation heating and worst. that scenario won't happened for sure. especially if governments in the future could cooperate with bitcoin user and even use bitcoin blockchain technology which it's happening now slowly.
