For the first part, you are so wrong, and it shows that you do not understand economics and national security. Without writing stories or mincing words, just research how many times the USA and some other top countries have changed the face of their currencies in the past 2 decades. You should also research the reasons for that so that you will be rightly enlightened about this.
Those who do not dare to openly protest against the government's work and go on social networks to complain are often people who do not understand anything about the country's economy and always like to blame others if they encounter difficulties.
Suppose even if what OP said is true then what is the more important point of this discussion if our opinions don't reach the government or we don't dare to stand up against what they do? If we cannot prevent them or dare not fight them, we should find ways to adapt and save ourselves. Hanging out on the internet and saying bad things about our country doesn't make us any less poor.
Let me start by saying that the first point of the OP in which he talked about the redesigning of the country's currency is certainly not valid because it shows the lack of understanding of the benefits of what is an international practice. But for the second point in which he talked about the corruption through infrastructural development, of course, it is so valid and it happens in many countries of the world. But still, corruption comes in different degrees/forms and infrastructural development might not be the case in some countries if such country is the kind that is strict with auditing when it comes to project allocation and execution.
Nevertheless, as you said, let's assume that such is the case, or generally, we are talking about the corrupt government that is making living difficult for the masses, well, the social medial is power and it's another good medium for people to reach out to the government, only that people do not take it seriously.
Social media attacks have been productive in the past, because that is the way many people can make their voice known, unlike the physical activism that demands your presence, more money and ruggedity. In my country, I've seen the government changing their minds because people called them out on social media in many cases. Even social media is a place where a petitions to be signed by the masses for appropriate bodies to know for subsequent action and sanctions would be known by connecting people to it for a redirect to the petition page. This makes petitions gains more popularity and has helped enough, even to let the powerful people and the highest sanctioning bodies of the world know about what people are facing in the hands of the government and private companies/individuals.
