Sure you can pressure people to transfer money from banks to you. But that will be easier to trace and the transactions could just be reversed. If moving all your wealth the bank is likely to ask some questions, maybe want to see you in person.
With crypto the philosophy is “be your own bank”. It’s like keeping your money under the mattress. So you are a much more promising target.
e.g. you have not had a wonderful windfall of someone mistypes an account number and send you a $1 million. You are in fact obligated to report the issue and not simply go "great!" and start spending the money, tonthe point that you can be held legally liable.
It's not 100% but as people are fond of saying: we do live in a society, it's hardly onerous.
Me kidnapping you probably isn't going to yield me much money from a bank. And robbing a bank is a death sentence.
In my country, transfers of very large sums often require upping the transaction limit by visiting the bank branch, filling out a form and then submitting it at which point it’ll be accepted in a few days.
While obviously inconvenient when trying to transfer funds for investments, etc. it’s easy to see why the system prevents fraud of this sort.
2) Privacy focused currencies like Monero make it exceedingly difficult to attribute transactions to specific individuals.
“Be your own bank” makes a cool bumper sticker but it’s like saying “be your own pilot” or “do your own surgery” in terms of complexity and risk. There’s a reason why these things traditionally involve teams of people with various safety precautions baked in to make attacks riskier.
In all seriousness I think most people relate to kidnapping and mutilation and not wanting it to happen to them.
I mean it’s not like the traditionally rich receive much love.
