end to cash or factual control?

It is a subject that is very present and every minute, who would have thought 30 or 40 years ago that, in the not too distant future, they would stop using the coins and tickets for day-to-day shopping ?.
In a globalized world, the use of credit cards and app(s) is a form of security in the face of skepticism about the management of sovereign currencies and the growing enthusiasm in alternative forms of payment, and greater control of the cost of using currencies physical

But what else is behind this? For example, in the United States, 90% of banknotes in circulation have detectable cocaine residues, we usually associate drug trafficking with the use of weapons and the handling of a large amount of money, the latter being in total cash, which it allows them to carry out transactions outside the financial system, without being easily tracked by the authorities.

But not only that, cash serves, for example, so that corruption occurs in different areas, a known case is when you want to offer a bribe to a police officer so that he does not infringe.

This kind of facts without cash could not happen, what do I mean by this? It is another measure of control on the part of the financial system and / or the state to keep us "guarded", and it would not seem strange, if the state is capable of much worse things.

Although for some people they like the idea of ​​not having to pay with paper but what about the elderly people, who do not have access to the app(s), those who do not even have a debit card, it is undoubtedly for them and for other factors that cash continues to work, Do not you believe it?

Beyond leaving the papers to pay, is how technology has influenced the new forms of control that the financial system or the state can have on us through credit cards, mobile application, etc. However, another question is, does Chile's existing trade have the proper system to pay through this medium? Is there a lack of national coverage for us to put aside cash? What do you think?
