Who takes responsibility for a thief who stole someone's digital goods and escapes without punishment in decentralized cyberspace?
Decentralized cyberspace for not everyone. It's not for granny and grad pas who do not know how to use a keyboard, how to browse internet and exchange messages securely. If you have not heard about encryption, done a little study about cryptography, if you do not know how to keep digital assets safely then crypto is not for you. For your own fault do not blame and entire idea.
To answer your question in one word,
YouYou are responsible to secure your asset.
Don't agree and also you've missed the subject which is
the thief.
Actually, no one can steal cryptos without the owners who made mistakes while storing their private keys. So the actual owner is responsible if he ever loses his crypto assets.
I still know people who save their private key in Google keep and in another digital platform that they think is secure. They argue google does not have anything else to do to check what I have stored in my Google keep or they think there will never be a data loss in google or in those digital platforms. If anyone is that much stupid then let them lose their money. Let them learn from the mistakes when they will not simply learn from others' experiences.
Negative, at least there is always the possibility of a hard bribe irl from the criminal intelligence done in cyberspace. Not to mention new ultra hi-tec spyware bots which are able to copy everything 'interesting' you typed on your comp in complete stealth mode.
Son, if tomorrow somebody kidnaps or rapes your child, you, like a keyholder of your child's freedom, will be responsible because you haven't cared enough, right?
Are you saying kidnapping and rapes are not happening now and they are not asking to give you money? You are also saying every kidnapping and rape happened so far, the bad guy asked for bitcoin or cryptocurrency to give back your child?
Again, you've missed the subject. When somebody rapes or kidnaps your daughter/son he/she is committing a crime of the first grade, second grade is the bribe and it really doesn't matter if she/he/they asked to be paid in cryptocurrency, fiat, or anything else valuable.
Pablo is not dead.
I wonder if Pablo still knows how to create a bitcoin wallet.
It was just a matter of metaphor.
Actually, even at the time of Pablo, there was a Kali cartel who won over Pablo at the end. So, can you imagine what happens today and how some highly educated leaders of criminal cartels are running their businesses?
