As for the constant surveillance , i'm on the side who believes that cameras should be anywhere .
Then we fundamentally disagree. The state does not have the right to constantly monitor its entire population "just in case".
The problem is that there's still no framework for these data to be handled "only" by authorities just in cases that a crime is committed .
Because that is an impossible fantasy. Any and all data collected under already existing surveillance programs is used by the government for literally any purpose they want, including being sold to third parties and shared with foreign governments, and there is nothing you can do about it.
Imagine a world where you would know that if you commit a crime you are almost 100% busted . Would you commit that crime ?
Show me evidence that mass surveillance has prevented a single terrorist attack.
There is none.You share things that you want with those you want .
And I, and many others, don't want random blockchain analysis companies, centralized exchange, governments, and so forth, spying on all our bitcoin transactions, holdings, addresses, and wallets. And so we use privacy enhancing tools.
