• tacking of payments gives those in power (banks, [bad] governments,…) Mechanism to completely profile and manipulate you. Your spendings says EVERYTHING about you. You might not care because you’re living in peaceful and stable (e.g. not in economic crisis like Venezuela) times, but the world and many governments are visibly changing for the worst. It gives them unlimited power to introduce any kind of taxes and fines or means of blocking you from moving away with your money to somewhere else. You don’t agree? They can still get to your money.
• limiting cash or anynomous payments takes away your financial freedom and strongly increases your dependency on banks. Banks put limits on your money that you can’t fully control, they block your transactions for whatever they find suspicous. They can charge you whatever they want. There’s a lot of corruption and money laundering with banks, that are the the most regulated institutions in the world ( except for armies probably), proving that even with a lot of control and legislation, those in power can still do whatever the fuck they want. Banks also take risks with your money and there have been crisises caused by them before. Most of them invest in oil, war and other ventures that are profitable for them. They manipulate markets for profit and for the worse of the common man. There’s a lot you can read about those things. Becoming so strongly dependant on banks give governments limitless power on what to do with your money and block it whenever they want. Truckers protested against government in Canada => bank accounts blocked.

Whether or not some or all of these examples matter to you, one thing you have to understand and always defend is: you are the boss of your of money. Your ownership and control over your money is evenly linked to how much freedom you have.

Another thing you also have to understand, even if you think full visibility and control for governments is a good thing to solve crime, corruption and/or money laundering: there are and have ALWAYS been black markets. And the worse countries are off, the stronger these markets become.
