I reread the introduction - but I still don't understand what is the reason? Is the author not saying something or deliberately omitting some nuances? Perhaps the bank was problematic, but the author decided to ignore the warnings? Perhaps the counterparties were not clean on their hands or fell under financial monitoring, which they also always inform about? There must be real reasons and grounds for blocking funds. Just like that "because we wanted it" can only be in countries with totalitarian or criminal regimes. Can the author publish funds blocking protocols, official letters? It will be transparent, understandable and open ... And this looks one-sided
governments and banks can steal at will buddy, better get with the program.
In fact, after making a deposit at a bank it is no longer considered legally your money, it's an obligation on the bank to repay, i.e. it is a loan.
This is what all these "bail-in" laws have been put in place for, "The Great Reset" is coming. Some stupid people have too much money loaned to the banks ... and the stupid governments have too many debts to pay off after wasting it on all manner of hare-brained (socialist) schemes. Match made in heaven.
Somewhere I may agree with your thoughts, but not everything is so bad and a little wrong

For example, in my country there is a so-called "deposit guarantee fund", which, albeit not fully, but insures such situations. The meaning of this fund is that the state fund accumulates funds at the expense of the same commercial banks, and guarantees that at the expense of this fund, if the bank cannot fulfill its obligations, an amount of up to $ 12k will be paid. This, of course, does not compensate for a $ 50k deposit, but most depositors do not keep such amounts on deposits.
And what happened in Cyprus is a reaction to the criminal acts of the government, the government that the people themselves chose and allowed to bring the economy to such a state. I will say this - I have been to Cyprus often (as a tourist), so the population there is quite lazy, although in their situation they would have to try harder and work better. But all the time they were waiting for handouts from the EU, aid, loans, i.e. waited for someone to solve their problems for them. The result is quite predictable, and private businesses suffered by inertia ...
