Before internet, people have been doing business and there are even companies that have survived for centuries and during those dark days, that was when they witnessed some of their massive growth. Internet comes with its own advantage but it does not means that without it, people wont still find a way to transact and do business with one another. Now when government shut down the internet, while businesses whose existence relied on that, they would surely have their reason for doing that and that is what the citizens needs to find out whether their reasons are valid or not.
It is true that businesses existed before the Internet but right now many of them depend on the Internet to reduce costs and to be more effective if you take it away then things will get ugly really fast, just think of restaurants, for the most part people are avoiding restaurants where I live but they have been able to remain open thanks to services like Uber Eats that allow you to order from them, if that is taken away I can assure you they will collapse in a matter of weeks or months and that is never good for the economy.
